The SuperH Mobile CEU hardware supports 16-bit width bus,
so extend the soc_camera code with SOCAM_DATAWIDTH_16.

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.

Makes SoC camera videobuf independent. Includes all necessary changes for
PXA camera driver (currently the only driver using soc_camera in the mainline).
These changes are important for the future soc_camera based drivers.

The proper fix were applied at -git. Re-apply the missing parts with the new
base.

Reverted several changes on soc_camera
From: Mauro Carvalho Chehab <mchehab@infradead.org>
As asked by Guennadi:
Mauro, please, drop commits 2f4a87873f13924871d7bb82e27d02d0e16fbe02 and
9b7d577c508e7765860e599c0e98d4ac3fbaa2aa from your tree and replace
5f1e5244ee6b9f139a262d5e7a930a41488afbbe with the version below.
Due to that change, that happened on v4l-dvb -git tree, several patches broke.
This patch reverts all broken stuff, keeping this tree in sync with v4l-dvb
-git tree.
I'm waiting for Guennadi to fix the broken patches and ask me to pull them
again.

All drivers should provide a spinlock to be used in videobuf operations.

Function pointers and the driver owner are not expected to change
throughout soc-camera host's life. Extract them into an operations struct.

In case of muliple cameras, handled by the same driver, they can support
different picture formats, therefore formats and num_formats cannot belong
to soc_camera_ops, which is only one per driver, move them to
soc_camera_device, which is one per device instance. OTOH, probe and
remove methods are always the same, move them to soc_camera_ops.
Thanks to Eric Miao for making me look at this code again:-)

Improve hardware parameter negotiation between the camera host driver and
camera drivers. Parameters like horizontal and vertical synchronisation,
pixel clock polarity shall be set depending on capabilities of the
parties.

Only attach cameras to the host interface for probing, then detach until
open. This allows platforms with several cameras on an interface,
physically supporting only one camera, to handle multiple cameras and
activate them selectively after initial probing. The first attach during
probe is needed to activate the host interface to be able to physically
communicate with cameras.

This driver provides an interface between platform-specific camera
busses and camera devices. It should be used if the camera is connected
not over a "proper" bus like PCI or USB, but over a special bus, like,
for example, the Quick Capture interface on PXA270 SoCs. Later it should
also be used for i.MX31 SoCs from Freescale. It can handle multiple
cameras and / or multiple busses, which can be used, e.g., in
stereo-vision applications.
