The AMD USB host controller (1022:43f7) does not enter PCI D3 by default
when nothing is connected. This is due to the policy introduced by
'commit a611bf473d1f ("xhci-pci: Set runtime PM as default policy on all
xHC 1.2 or later devices")', which only covers 1.2 or later devices.

Therefore, by default, allow RPM on the AMD USB controller [1022:43f7].

Fixes: 4baf12181509 ("xhci: Loosen RPM as default policy to cover for AMD xHC 1.1")
