usb: gadget: udc: Remove redundant initialization for udc_driver

There is a warning reported by coccinelle:

./drivers/usb/gadget/udc/renesas_usbf.c:3381:3-8:
		No need to set .owner here. The core will do it.

The module_platform_driver() will set "THIS_MODULE" to driver.owner
when register a driver for platform-level devices, so it is redundant
initialization to set driver.owner in udc_driver statement. Remove it
to silence the warning.
