Revert "xhci: clear root port wake on bits if controller isn't wake-up capable"
commit 9b41ebd3cf0f68d8cad779d3eeba336f78262e43 upstream.
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.

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