USB: EHCI: HSIC: Guard against late remote wakeup during suspend

Protect against the possibility of receiving a remote wakeup event
when the controller is about to enter suspend. If it happens, abort
the suspend sequence so the controller can handle it normally,
otherwise it may result in a stuck PHY due to a hardware limitation
when re-entering suspend instead of acknowledging the event within
the spec-defined 20ms of resume signaling.
