  Workaround CSS timeout on AMD SNPS 3.0 xHC

Status in linux package in Ubuntu:

Bug description:
  Raven Ridge xHC may fail to suspend, causes the USB stops working, and blocks 
the system entering system-wide suspend.

  It's a hardware/firmware bug, workarounded by bailing out suspend function if 
it ever fails, and reset the xHC in next resume function.

  After applying the patch, the USB works, and the system can enter S3 

  [Regression Potential]
  Minimal. This workaround only applies to AMD Raven Ridge xHC.
