This adds V4L2_MBUS_FMT_RGB888_1X24 input format support
which is used by the ADV7612 chip.

This is actually not related to this patch, but I just looked at the 
driver again - at the rcar_vin_setup() function, the

	/* output format */
	switch (icd->current_fmt->host_fmt->fourcc) {

selection. The default case of that switch statement returns an error, 
whereas the driver claims to support a pass-through mode. That looks like 
a ubg to me, but it should be fixed in a separate patch.

Thanks
