PCI: Increase D3 delay for AMD Renoir/Cezanne XHCI
[ Upstream commit e0bff43220925b7e527f9d3bc9f5c624177c959e ]
The Renoir XHCI controller apparently doesn't resume reliably with the
standard D3hot-to-D0 delay. Increase it to 20ms.
[Alex: I talked to the AMD USB hardware team and the AMD Windows team and
they are not aware of any HW errata or specific issues. The HW works fine
in Windows. I was told Windows uses a rather generous default delay of
100ms for PCI state transitions.]
