V4L2 pixel formats are supposed to describe video frames in memory. To
describe the pixel format on the hardware bus between display interface
and encoders, use media bus formats, which are more expressive.

This allows to get rid of the custom GBR24 and LVDS666 fourccs.

+ * These bus formats uniquely identify data formats on the data bus. Format 0
+ * is reserved, MEDIA_BUS_FMT_FIXED shall be used by host-client pairs, where
+ * the data format is fixed. Additionally, "2X8" means that one pixel is
+ * transferred in two 8-bit samples, "BE" or "LE" specify in which order those
+ * samples are transferred over the bus: "LE" means that the least significant
+ * bits are transferred first, "BE" means that the most significant bits are
+ * transferred first, and "PADHI" and "PADLO" define which bits - low or high,
+ * in the incomplete high byte, are filled with padding bits.
+ *
+ * The bus formats are grouped by type, bus_width, bits per component, samples
+ * per pixel and order of subsamples. Numerical values are sorted using generic
+ * numerical sort order (8 thus comes before 10).
+ *
+ * As their value can't change when a new bus format is inserted in the
+ * enumeration, the bus formats are explicitly given a numerical value. The next
+ * free values for each category are listed below, update them when inserting
