v4:
- added the datasheet labels
- added Reviewed-by
v3:
- added flags
- added delay
v2:
- changed bpc to 6
- set max value of pixelclock
- increased hfront_porch and hback_porch
- dropped connector-type
adding of bus_format = MEDIA_BUS_FMT_RGB666_1X18 results in wrong colors.
omitting bus_format and using some default is better (Tux Pinguin is colored
fine)
