We'd been asked if the S01x YUV formats could be supported on Pi5 as some
software codecs produce them.
The answer was yes, so this patch adds them and the P01x formats.

Changes in v2:

  each format (suggested by Maíra)

I tested this with the Gstreamer MR from 1 and can confirm that the 
formats P010, P012, P016, S010 and S012 work as expected.

Unfortunately S016 is not supported by Gstreamer yet - however chances 
seem high that it works as well.

Thus the series is:

Thanks for testing.

In combination with my MR to libdrm/modetest to support these
formats[1], I'm happy that S016 works.
Your testing through Gstreamer gives me confidence that I haven't
messed up both my kernel patch and modetest setup in the same way :-)

Thanks again
