Subject: usb hotplug broken on v6.5.12

Hej,

usb hotplug doesn't work for me running stable kernel v6.5.12 on an AMD
based Thinkpad t495s. Bisect pointed to 7b8ae3c24ef ("xhci: Loosen RPM as
default policy to cover for AMD xHC 1.1") - which is 4baf1218150 upstream.

Reverting that from 6.5.12 fixes the issue for me.
Current upstream rc kernel contains this patch but doesn't show the issue.

Regards,
Sebastian
