usb: udc: implement DM versions of usb_gadget_initialize()/_release()/_handle_interrupt()
When DM_USB_GADGET the platform code for the USB device must be replaced by calls to a USB device driver. usb_gadget_initialize() probes the USB device driver. usb_gadget_release() removes the USB device driver.
