Roger Quadros 4abc5ee334 usb: dwc3: fix fault at system suspend if device was already runtime suspended
commit 9cfb31e4c8 upstream.

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.
