xhci: Loosen RPM as default policy to cover for AMD xHC 1.1
[ Upstream commit4baf121815
] The AMD USB host controller (1022:43f7) isn't going into PCI D3 by default without anything connected. This is because the policy that was introduced by commita611bf473d
("xhci-pci: Set runtime PM as default policy on all xHC 1.2 or later devices") only covered 1.2 or later. The 1.1 specification also has the same requirement as the 1.2 specification for D3 support. So expand the runtime PM as default policy to all AMD 1.1 devices as well. Fixes:a611bf473d
