It adds the new CID for setting Scenemode. This CID is provided as
menu type using the following items:
enum v4l2_scenemode {
V4L2_SCENEMODE_NONE = 0,
V4L2_SCENEMODE_NORMAL = 1,
V4L2_SCENEMODE_PORTRAIT = 2,
V4L2_SCENEMODE_LANDSCAPE = 3,
V4L2_SCENEMODE_SPORTS = 4,
V4L2_SCENEMODE_PARTY_INDOOR = 5,
V4L2_SCENEMODE_BEACH_SNOW = 6,
V4L2_SCENEMODE_SUNSET = 7,
V4L2_SCENEMODE_DAWN_DUSK = 8,
V4L2_SCENEMODE_FALL = 9,
V4L2_SCENEMODE_NIGHT = 10,
V4L2_SCENEMODE_AGAINST_LIGHT = 11,
V4L2_SCENEMODE_FIRE = 12,
V4L2_SCENEMODE_TEXT = 13,
V4L2_SCENEMODE_CANDLE = 14,
};
