Bug description:
[Impact]
Raven Ridge xHC may fail to suspend, causes the USB stops working, and blocks
the system entering system-wide suspend.
[Fix]
It's a hardware/firmware bug, workarounded by bailing out suspend function if
it ever fails, and reset the xHC in next resume function.
[Test]
After applying the patch, the USB works, and the system can enter S3
consecutively.
[Regression Potential]
Minimal. This workaround only applies to AMD Raven Ridge xHC.
