nit: Since this isn't really about using the CSIS device or not, but
rather about the interface that the sensor is connected with, could we
instead say "when a parallel interface is used"?

Should we also handle MEDIA_BUS_FMT_S5C_UYVY_JPEG_1X8 as in the CSI
case? The S5C73M3 sensor supports the parallel interface as well.
