Subject: [PATCH 2/2] usb: gadget: atmel_usba_udc: remove release function

As the driver call usb_add_gadget_udc --> usb_add_gadget_udc_release
with NULL as release parameter, so it will use usb_udc_no_release.
So, the release in driver won't used, remove it.

And at the same time, in the usb_add_gadget_udc_release will set the
gadget name, so remove it also in driver.
