usb: gadget: omap_udc: Make it CCF clk API compatible
The driver, OMAP1 specific, now omits clk_prepare/unprepare() steps, not
supported by OMAP1 custom implementation of clock API. However, non-CCF
stubs of those functions exist for use on such platforms until converted
to CCF.
Update the driver to be compatible with CCF implementation of clock API.
