[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.
