usb: renesas-xhci: Fix handling of unknown ROM state



The ROM load sometimes seems to return an unknown status
(RENESAS_ROM_STATUS_NO_RESULT) instead of success / fail.

If the ROM load indeed failed this leads to failures when trying to
communicate with the controller later on.

Attempt to load firmware using RAM load in those cases.
