[v2,0/5] media: v4l: Add Broadcom sand format to the list of V4L formats

This is in preparation for attempting to upstream the Rpi H265 decoder
as these formats are the only ones the hardware can decode to. They are
a column format rather than a tile format but I've added them to the
list of tiled formats as that seems the closest match.

V4L2_PIX_FMT_NV12_C128 matches DRM format NV12 with modifier
DRM_FORMAT_MOD_BROADCOM_SAND128_COL_HEIGHT(ch) and
V4L2_PIX_FMT_P030_C128 matches DRM format P030 with the same modifier.

version 2:
- Add franctional bpp support from the "AV1 stateless decoder for
  RK3588" patch set.
- Add description to v4l2-ioctl.c
- Add format info to v4l2-common.c
- Rework documentation in line with comments
