usb: gadget: convert all users to the new udc infrastructure

Browse Source 
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.
