[media] v4l2 core: add the missing pieces to support DVI/HDMI/DisplayPort
These new controls and two new ioctls make it possible to properly support VGA, DVI-A/D/I, HDMI and DisplayPort connectors. All these controls and the ioctls are all at the sub-device level. They are meant for V4L2 bridge/platform drivers or to be accessed on embedded systems through /dev/v4l-subdev* device nodes.
