+ a bunch of AMD guys
Please don't submit quirks for AMD systems without talking to AMD about
if they make sense.

When the xHC host is runtime suspended, the device connects to it will be
disconnected while trying to use it.
The quirk in commit 2a632815683d ("usb: xhci: Workaround for S3 issue on
AMD SNPS 3.0 xHC") also works for this issue, so added its ID to the
quirk, too.

Is this system that you're finding this bug already launched? This
looks like a BIOS bug.
If it's not launched we should fix it from BIOS, reach out to AMD off
list to talk about it.
