Subject: [PATCH v2 0/2] drm: vc4: Add support for additional 10/12/16bit
 YUV plane formats

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:
- Swapped from adding an extra bool hvs6_only to having a min_gen for
  each format (suggested by Maíra)
