REGRESSION: Renesas USB host broken after commit d143825baf15

Hi,

the recent patch landed in 5.13.2 stable tree from the upstream commit d143825baf15 ("usb: renesas-xhci: Fix handling of unknown ROM state") seems causing a regression on a few machines, as reported on openSUSE Bugzilla:
https://bugzilla.opensuse.org/show_bug.cgi?id=1188485
https://bugzilla.opensuse.org/show_bug.cgi?id=1188515

Reverting it on top of 5.13.3 fixed the problem, so it's likely the cause. Could you guys take a look?

I've sent out a revert patch.

I think the driver has more problems but I'll tackle that in a follow up patch, lets get this unbricked, first.

OK, thank you for the information!
