UBUNTU: SAUCE: PCI: Avoid ASMedia XHCI USB PME# from D0 defect

BugLink: https://bugs.launchpad.net/bugs/1858988
The ASMedia USB XHCI Controller claims to support generating PME# while
in D0:

01:00.0 USB controller: ASMedia Technology Inc. Device 2142 (prog-if 30 [XHCI])
        Subsystem: SUNIX Co., Ltd. Device 312b
        Capabilities: [78] Power Management version 3
                Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0+,D1-,D2-,D3hot-,D3cold-)
                Status: D0 NoSoftRst+ PME-Enable+ DSel=0 DScale=0 PME-

However PME# only gets asserted when plugging USB 2.0 or USB 1.1
devices, but not for USB 3.0 devices.

So remove PCI_PM_CAP_PME_D0 to avoid using PME under D0.
