usb: gadget: convert all users to the new udc infrastructure
peripheral drivers are using usb_add_gadget()/usb_del_gadget() to register/unregister to the udc-core. The udc-core will take the first available gadget driver and attach function driver which is calling usb_gadget_register_driver(). This is the same behaviour we have right now. Only dummy_hcd was tested, the others were compiled tested.
