[PATCH 01/07] soc_camera: Remove default spinlock operations

[Magnus Damm <magnus.damm@gmail.com>]

This patch removes the default spinlock_alloc() and spinlock_free()
functions. The pxa_camera.c driver is providing it's own spinlock
callbacks anyway. With this patch spinlock callbacks are required
when registering the host.

This is ground work for the next per-host videobuf queue patch.
