Fixes, which might have practical impact, however things were broken for
long enough to justify pushing it regular path:
1. ARM Juno: shorten node names for thermal zones, because Linux drivers
have strict limit of 20 characters.
2. HiSilicon: correct size of GIC GICC address space and add missing
GICH and GICV spaces, add cache info to properly describe cache
topology and solve kernel boot warning.
Several cleanups:
1. Use capital "OR" for multiple licenses in SPDX.
2. Correct white-spaces for code readability.
3. Fix W=1 dtc compiler warnings, which should not have practical
impact for Amazon, APM, Cavium, Realtek, Socionext Uniphier and
Spreadtrum like:
- missing unit addresses,
- nodes not belonging to soc node,
- not using generic node names,
- few incorrect unit addresses.

The "arm,armv8-pmuv3" compatible is intended only for s/w models. Primarily,
it doesn't provide any detail on uarch specific events.
There's still remaining cases for CPUs without any corresponding PMU
definition and for big.LITTLE systems which only have a single PMU node
(there should be one per core type).

The GICv3 ITS is an MSI controller, therefore its node name should be
'msi-controller'. The ITS node is also expected to have '#msi-cells'.
Add it on Thunder as there are no users. Thunder2 uses 'msi-parent', but
Robin says that should be 'msi-map' instead and I'm not sure what's
correct for it.
The unit-addresses of both the ITS and main GIC node on thunder2 are also
wrong, so fix them while we're here.

The 'arm,armv8' compatible string is only for software models. It adds
little value otherwise and is inconsistently used as a fallback on some
platforms. Remove it from those platforms.
This fixes warnings generated by the DT schema.

The ARM architected timer specification mandates that the interrupt
associated with each timer is level triggered (which corresponds to
the "counter >= comparator" condition).
A number of DTs are being remarkably creative, declaring the interrupt
to be edge triggered. A quick look at the TRM for the corresponding ARM
CPUs clearly shows that this is wrong, and I've corrected those.
For non-ARM designs (and in the absence of a publicly available TRM),
I've made them active low as well, which can't be completely wrong
as the GIC cannot disinguish between level low and level high.
The respective maintainers are of course welcome to prove me wrong.
While I was at it, I took the liberty to fix a couple of related issue,
such as some spurious affinity bits on ThunderX, and their complete
absence on ls1043a (both of which seem to be related to copy-pasting
from other DTs).
