usb: dwc3: fix fault at system suspend if device was already runtime suspended
If the device was already runtime suspended then during system suspend
we cannot access the device registers else it will crash.
Also we cannot access any registers after dwc3_core_exit() on some
platforms so move the dwc3_enable_susphy() call to the top.
