Bug Description

[Impact]
AMD request to backport USB4 support patches.

[Fix]
Add some quirks/fixes for AMD USB4 controller.

[Test]
I don't have the hardware, so it requires AMD to validate the backport.

[Where problems could occur]
- The enumeration of switch ports is changed, the effect is unknown.
- The QUIRK_AUTO_CLEAR_INT is only applied to Intel TBT controller. I've
  heard that Asmedia also produces TBT controllers but I've never seen
  one. So the change will affect other vendor's TBT controller, if they
  exist.

So only apply it to Impish, Unstable and OEM-5.13 to limit regression
risk.

It doesn't break Intel Thunderbolt per my limited testing.
