[media] V4L: Add camera scene mode control

Add control for the scene mode feature available in image sensor
with more advanced ISP firmware. The V4L2_CID_SCENE_MODE menu
control allows to select a set of parameters or a specific image
processing and capture control algorithm optimized for common
image capture conditions.
