[media] V4L: Add driver for OV9650/52 image sensors

This patch adds V4L2 sub-device driver for OV9650/OV9652 image sensors.
The driver exposes following V4L2 controls:
- auto/manual exposure,
- auto/manual white balance,
- auto/manual gain,
- brightness, saturation, sharpness,
- horizontal/vertical flip,
- color bar test pattern,
- banding filter (power line frequency).
Frame rate can be configured with g/s_frame_interval pad level ops.
Supported resolution are only: SXGA, VGA, QVGA.
