media: rcar-vin: Unconditionally unregister notifier on remove
If the VIN device is part of a group of VIN devices (all Gen3 boards)
there is no reason to only unregister the group notifier if the VIN that
registers the notifier is removed. The VIN that registers the notifier
is always the last VIN device to be bound, so keeping the notifier
around after any VIN is unbound creates an unbalanced state where no VIN
in the group is operational.
Fix this by unconditionally unregistering the notifier when any VIN
device is unbound. Unregistering the notifier will lead to unbound()
being called and all video devices exposed by any VIN instance to be
removed.
The lock was only needed to protect the check which VIN registers the
notifier and is no longer needed.

media: videobuf2-v4l2.c: add vb2_video_unregister_device helper function
If a driver calls (_)vb2_fop_release(), then such a driver should also
call vb2_video_unregister_device() instead of video_unregister_device().
This helper will call vb2_queue_release() if a filehandle is marked as
owner of the queue. This ensures that at unregister time any streaming
is cancelled and all buffers are returned to userspace.
This is very useful for complex drivers since this stops all streaming
in all subdevs in the pipeline controlled by this video device. Otherwise
this would be delayed until the owner filehandle is closed, which can be
quite some time later.
Bonus points for ordering the includes :-)
