[media] soc-camera: remove struct soc_camera_device::video_lock
Currently soc-camera has a per-device node lock, used for video operations
and a per-host lock for code paths, modifying host's pipeline. Manipulating
the two locks increases complexity and doesn't bring any advantages. This
patch removes the per-device lock and uses the per-host lock for all
operations.
