Kai-Heng Feng 7e8ce0e2b0 x86/PCI: Avoid AMD FCH XHCI USB PME# from D0 defect
The AMD FCH USB XHCI Controller advertises support for generating PME#
while in D0.  When in D0, it does signal PME# for USB 3.0 connect events,
but not for USB 2.0 or USB 1.1 connect events, which means the controller
doesn't wake correctly for those events.

  00:10.0 USB controller [0c03]: Advanced Micro Devices, Inc. [AMD] FCH USB XHCI Controller [1022:7914] (rev 20) (prog-if 30 [XHCI])
        Subsystem: Dell FCH USB XHCI Controller [1028:087e]
        Capabilities: [50] Power Management version 3
                Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0+,D1-,D2-,D3hot+,D3cold+)

Clear PCI_PM_CAP_PME_D0 in dev->pme_support to indicate the device will not
assert PME# from D0 so we don't rely on it.
