The clock seems to be optional at probe time, if not found it's set
to NULL. However this was not the case in the function nop_usbphy_init
which exits with error if the clock cannot be enabled.
Make the clock optional also during the nop_usbphy_init by trying to
do the clock init only if the clock has been found during probe.
