The driver currently hides this format by always enabling the post-processor engine, and therefore offering NV12 directly. This is done without using the logic in hantro_postproc.c and therefore makes it difficult to add VP9 cleanly. Since fixing this is not easy, add a small quirk to force NV12 if HEVC was configured, but otherwise declare NV12_4L4 as the pixel format in imx8mq_vpu_g2_variant.dec_fmts. This will be used by the VP9 decoder which will be added soon.
