In preparation for adding field decoding support, convert the byte arrays
for reflist into array of struct v4l2_h264_reference. That struct will
allow us to mark which field of the reference picture is being referenced.

nit: will be nice to preserve to reverse Xmas coding style, but only if
you'll need to make v5 with more important changes
