Subject: [PATCH] media: ov5647: Add extra 10-bit sensor modes.

The 8-bit VGA mode remains, we add the following 10-bit modes:

Mode 0: 2592x1944 full resolution.

Mode 1: 1920x1080 full resolution, but centre-cropped.
(This mode achieves 30fps, mode 0 does not.)

Mode 2: 1296x972 full field-of-view 2x2 binned mode.

Mode 3: VGA full field of view mode.
