Systems with multiple host controllers will most likely have a different
NVM image for each controller but there is no guarantee that the device_id
within the NVM image varies from one controller to another.
To account for this, build a GUID that contains the last element of the
Thunderbolt controller's udev path.
Sample GUID strings from an XPS 9380 (which only contains one host controller):
```
Guid: 0f401ed2-b847-532a-adc8-3193fc737be6 <- TBT-00d408af-native
Guid: 420b0596-f5cb-5fd7-8416-c99d48ad8de9 <- TBT-00d408af-native-0000:05:00.0
```
This commit follows the presumption that the kernel will enumerate the controllers
in the same order every time.
Currently ICL shows up like this:
```
├─Unknown Device:
│ Device ID: d066959bf1b0da600f4fcaab5aa31cab3ff05eee
│ Summary: Unmatched performance for high-speed I/O
│ Current version: 71.00
│ Update Error: Missing non-active nvmem
│ Flags: internal|require-ac|registered
│ GUID: e72e778e-94f7-5ed2-b560-1c1262ee217c
```
Which isn't very useful to end users. Instead show the generic name
`Thunderbolt Controller` which matches the behavior change we've made
in UEFI FW and Touchpad FW items too.
```

Also, quite the messages about missing vid/did as these won't exist
on ICL either.
Use this attribute to determine whether or not to try to read 'native'
from the Thunderbolt NVM image at probe time.
This attribute is new to kernel 5.5.
There are commits to the Thunderbolt kernel driver that make sure
that the upgrade process goes smoothly. If these commits aren't
present then it will look like a fwupd problem, when it's actually
a kernel problem.
When this issue was reported it appeared that commit
e4be8c9b6a
was missing from the locally tested kernel, but it's impossible
to determine that from userspace.
Prevent running the thunderbolt plugin on older kernels than that
set in `$sysconfdir/fwupd/thunderbolt.conf`.
By default that is set to 4.13.0, but if a distribution vendor has
backported all the necessary support it can be decreased to a lower
version for distro packages.
This controller isn't flashable in fwupd, but fwupd can display information
about it.
* Use a generic device ID (similar to safemode)
* Build device name attribute from DMI data
This leads to madness, as some formats are supersets of the detected types,
e.g. 'intel-me' is detected as 'quad' and 'bcd' is detected as 'pair'.
Where the version format is defined in a specification or hardcoded in the
source use a hardcoded enum value, otherwise use a quirk override.
Additionally, warn if the version does not match the defined version format
Future metadata from the LVFS will set the protocol the firmware is expected to
use. As vendors love to re-use common terms like DFU for incompatible protocols,
namespace them with the controlling company ID with an approximate reverse DNS
namespace.
This also allows more than one plugin to define support for the same protocol,
for instance rts54hid+rts54hub and synapticsmst+dell-dock.
`g_ascii_strtoull` returns 0 and sets `errno` to `-EINVAL` only when
the base is invalid. It's hardcoded to `16` so this is impossible.
Reading `-EINVAL` from `errno` is incorrect in these circumstances.

Plugins are allowed to 'opt-out' of this behaviour using _RULE_INHIBITS_IDLE.
This should be used where waking up the hardware to coldplug is expensive,
either from a power consumption point of view, or if other artifacts are going
to be seem -- for instance if the screen flickers when probing display devices.
This functionality is also inhibited when the actual upgrade is happening,
for obvious reasons.
Admins can turn off this auto-sleep behaviour by editing the daemon.conf file.

We load the Thunderbolt controller firmware to see if the controller is in
native mode, as this changes the GUID. If the controller is asleep the firmware
is not cached by the kernel and it can take more than 4 seconds to read out
504kB of firmware.
We only need the first two 64-byte chunks, so only read what is required.
This speeds up fwupd starting substantially, and also means we don't have to
allocate a giant chunk of heap memory just to inspect one byte.

It wasn't hugely clear what the platform ID was actually meant to represent. In
some cases it was being used like a physical ID, in others it was a logical ID,
and in others it was both. In some cases it was even used as a sysfs path.
Clear up all the confusion by splitting the platform ID into two parts, an
optional *physical* ID to represent the electrical connection, and an optional
*logical* ID to disambiguate composite devices with the same physical ID.
Also create an explicit sysfs_path getter for FuUdevDevice to make this clear.
This allows WAIT_FOR_REPLUG to always work, rather than depending on the order
that the GUIDs were added, and that the kernel would always return the same
sysfs path (which it doesn't have to do, especially for hidraw devices).
As an example use case earlier development versions of a Thunderbolt module
may contain DROM corresponding to one model ID and transition to another
model ID. Even if lying about the GUIDs supported by the device via a
quirk the Thunderbolt validation will fail because the device isn't
intended for that system.
This should only be used during development.
Currently we only parse the nvm_version attribute according fwupd
expectations when the device is initially added. Elsewhere we just use
the raw version as is which might be problematic as the version format
can change in the middle (for example "33.02" vs. "33.2"). Fix this so
that fu_plugin_thunderbolt_udev_get_version () always returns parsed
version string.
Update self tests accordingly to have "parsed" version to which we
compare against.

Since the multi controller entry is part of the DROM and its place is
not fixed, it is possible (however unlikely) that the locations between
controller and the image are different. One scenario is that the new
image has typo in device or vendor name string fixed which could cause
the offset to be different.
To handle this case properly we need to read multi controller locations
of both controller and image separately, read their values and then
compare them against each other.

During review it was pointed out that the return value of
read_drom_entry_location () should be documented because it also returns
TRUE when an entry was not found from the DROM. Caller needs to look for
the location->offset in that case. Add a comment explaining this.

This reverts commit ed7acc7819.
As pointed out by @YehezkelShB during review the Titan Ridge IDs 0x15E8
and 0x15EB are for the NHI (the host controller). Windows SDK tool uses
them to keep track of different controllers but in Linux we don't need
them and can use the already existing bridge IDs.
There is no harm to have them listed but to avoid possible confusion in
future remove them.

Titan Ridge devices may contain multiple controllers so we need to make
sure the supplied NVM image multi controller number matches the
controller in question. This is pretty much same than we had for Alpine
Ridge (X of N) but the difference is that this multi controller
information is found in DROM instead and the location is not fixed.
For this reason we implement a generic DROM entry parser and use it to
dynamically fill in correct location of multi controller entry based on
the controller active firmware.
In addition to that we add a check for the NVM flash size just like we
do for Titan Ridge host.

Titan Ridge has same set of bits than Alpine Ridge telling whether the
Thunderbolt controller is in native or legacy mode. Add validation for
that.
