[patch] v4l: v4l2 API updates

[Gerd Knorr]

  Hi,

This patch has some minor updates to v4l2 API:

  * A new pixel format (V4L2_PIX_FMT_SBGGR8).
  * Adds some #defines for tv norms for convenience.
  * Allow to specify the video source to capture from on a
    per-frame basis.

please apply,

  Gerd
