Bug Description
===SRU Justification===
[Impact]
xHC stays at D0 when system is in S3. Unfortunately D0 can't generate PME# wakeup event, so USB device can't wake the system.
[Test]
Intel NUC can't be waken up by USB keyboard when the system is in S3.
With the patch, USB keyboard can wake up the system.
[Regression Potential]
Low.
The issue starts appearing from Gemini Lake, older generation hardware shouldn't get affected.
