NV20 and NV30 drm format have now been merged into mainline linux,
please add these missing formats. The patch below adds support for them
to rk356x part of vop2 driver.

drm/rockchip: vop2: Add NV20 and NV30 support
https://lore.kernel.org/linux-rockchip/20231025213248.2641962-1-jonas@kwiboo.se/

NV15/NV20/NV30 formats can be tested using modetest from latest main
of libdrm.

modetest: add support for DRM_FORMAT_NV{15,20,30}
