WIP: Hantro G1 H.264 support
The Hantro G1 H.264 hardware decoder parses slice headers itself, but it needs some assistance. Particularly, it needs to be told the size of the dec_ref_pic_marking() syntax element and the total size of the pic_order_cnt related syntax elements in bits.
WIP because this depends on gst-plugins-bad!729 (merged) and https://github.com/intel/libva/pull/332.
This can be used with https://github.com/bootlin/libva-v4l2-request/pull/26.
