From: Lu Baolu <baolu.lu@xxxxxxxxxxxxxxx>

commit ff8cbf250b44 ("xhci: clear root port wake on bits if controller isn't")
can cause device detection error if runtime PM is enabled, and S3 wake
is disabled. Revert it.
https://bugzilla.kernel.org/show_bug.cgi?id=85701

This commit got into stable and should be reverted from there as well.
