Don't populate the array 'registers' on the stack but instead make it
static const. Makes the object code smaller by 45 bytes.

In order to have subsytem agnostic media bus format definitions we've
moved media bus definition to include/uapi/linux/media-bus-format.h and
prefixed values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT.
Reference new definitions in all platform drivers.

This patch adds V4L2 driver for Samsung S3C24XX/S3C64XX SoC series
camera interface. The driver exposes a subdev device node for CAMIF
pixel resolution and crop control and two video capture nodes - for
the "codec" and "preview" data paths. It has been tested on Mini2440
(s3c2440) and Mini6410 (s3c6410) board with gstreamer and mplayer.
