For instance, on a G1 core, the decoder engine produces NV12 buffers and the post-processor engine can produce YUY2 buffers. The decoder engine expects motion vectors to be appended to the NV12 buffers, but this is only required for CODECs that need motion vectors, such as H.264. Fix the post-processor logic accordingly.

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.

Enable the G2 post-processor block, in order to produce regular NV12. The logic in hantro_postproc.c is leveraged to take care of allocating the extra buffers and configure the post-processor, which is significantly simpler than the one on the G1.
