drm/rockchip: vop2: Add NV20 and NV30 support

Add support for the 10-bit 4:2:2 and 4:4:4 formats NV20 and NV30.

These formats can be tested using modetest [1]:

  modetest -P <plane_id>@<crtc_id>:1920x1080@<format>

e.g. on a ROCK 3 Model A (rk3568):

  modetest -P 43@67:1920x1080@NV20 -F tiles,tiles
  modetest -P 43@67:1920x1080@NV30 -F smpte,smpte
