[media] v4l2: add v4l2_prio_state to v4l2_device and video_device
Integrate the v4l2_prio_state into the core, ready for use. One struct v4l2_prio_state is added to v4l2_device and a pointer to a prio state is added to video_device. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
