Bug Description
[Impact]
Sometimes USB hub on Dell TB16 stop working after S3.
[Fix]
Attempt to power cycle USB device when a it's stuck at eSS.Disabled
state, it's basically not recoverable.
[Test]
After applying the patch, USB ports and USB ethernet are still working
after 100 times S3 stress test.
Tested on other platforms and didn't observe any regression.
However, I have never seen any other USB device stuck in eSS.Disabled state,
so the code path wasn't executed at all.
[Regression Potential]
Low. This is a last resort attempt, in most cases this code path won't
be reached.
