MAINTAINERS: Mark UVC gadget driver as orphan

I haven't had time to maintain the UVC gadget driver for a long while.
Dan Scally confirmed he is also in a similar -ENOTIME situation with no
short term hope of fixing that. Being listed as maintainers doesn't help
progress, so mark the driver as orphan to reflect the current state.
