V4L/DVB (8338): soc_camera: Move spinlocks
This patch moves the spinlock handling from soc_camera.c to the actual
camera host driver. The spinlock_alloc/free callbacks are replaced with
code in init_videobuf(). So far all camera host drivers implement their
own spinlock_alloc/free methods anyway, and videobuf_queue_core_init()
BUGs on a NULL spinlock argument, so, new camera host drivers will not
forget to provide a spinlock when initialising their videobuf queues.
