Add a port used to connect the SuperSpeed output endpoint to a
Type-C connector.
Note that the MediaTek XHCI controllers are always in front of a
different controller handling the USB HS (usually, MTU3), so the
only port that this controller provides is SuperSpeed, while the
HighSpeed one comes from elsewhere.

For Gen1 isoc-in endpoint on controller before about SSUSB IPM v1.6.0, it
still send out unexpected ACK after receiving a short packet in burst
transfer, this will cause an exception on connected device, specially for
a 4k camera.
Add a quirk property "rx-fifo-depth" to work around this hardware issue,
prefer to use 3k bytes;
The side-effect is that it may cause performance drop about 10%, including
bulk transfer.

This reverts commit ebc4969ae1. That
commit was supposed to make the binding better reflect the MediaTek XHCI
hardware block by requiring all clocks to be present. But doing that
also causes too much noise in the devicetrees, since it requires
updating old MediaTek DTs to add clock handles for the fixed clocks, and
going forward every new clock added to the binding would require even
more updates.
The commit also didn't update the example to match the changes, causing
additional warnings.
Instead let's keep the clocks optional so that old devicetrees can keep
omitting the fixed clocks, and we'll just add the clocks as required on
new DTs.

All of the clocks listed in the binding are always wired to the XHCI
controller hardware blocks on all SoCs. The reason some clocks were made
optional in the binding was to account for the fact that depending on
the SoC, some of the clocks might be fixed (ie not controlled by
software).
Given that the devicetree should represent the hardware, make all clocks
required in the binding. Subsequent patches will make the DTS changes to
specify fixed-clocks for the clocks that aren't controllable.

There are 4 USB controllers on MT8195, the controllers (IP1~IP3,
exclude IP0) have a wrong default SOF/ITP interval which is
calculated from the frame counter clock 24Mhz by default, but
in fact, the frame counter clock is 48Mhz, so we should set
the accurate interval according to 48Mhz. Here add a new compatible
for MT8195, it's also supported in driver. But the first controller
(IP0) has no such issue, we prefer to use generic compatible,
e.g. mt8192's compatible.

These two HW of wakeup don't follow MediaTek internal IPM rule,
both use a specific way, like as early revision of mt8173.
Due to the index 2 already used by many DTS, it's better to keep
it unchanged for backward compatibility, treat specific ones without
following IPM rule as revision 1.x, meanwhile reserve 3~99 for
later revisions with following the IPM rule.
