Basavaraj Natikar 10bda0ec31 x86/PCI: Add quirk for AMD XHCI controller that loses MSI-X state in D3hot 
commit f195fc1e9715ba826c3b62d58038f760f66a4fe9 upstream.

The AMD [1022:15b8] USB controller loses some internal functional MSI-X
context when transitioning from D0 to D3hot. BIOS normally traps D0->D3hot
and D3hot->D0 transitions so it can save and restore that internal context,
but some firmware in the field can't do this because it fails to clear the
AMD_15B8_RCC_DEV2_EPF0_STRAP2 NO_SOFT_RESET bit.

Clear AMD_15B8_RCC_DEV2_EPF0_STRAP2 NO_SOFT_RESET bit before USB controller
initialization during boot.
