[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1846470

[Impact]
xHCI on AMD Stoney Ridge cannot detect USB 2.0 or 1.1 devices.

[Fix]
The xHCI in question doesn't have proper support for D0 PME, so strip it
from PM capability.

[Test]
The xHCI can detect USB 2.0 and USB 1.1 device with the fix.

[Regression Potential]
Low. Has limited scope and doesn't touch any driver code.
