Step '8.2.4.1 Decoding process for picture numbers' was missing in the
reflist creation logic, leading to invalid P reflists when a
->frame_num wraparound happens.
Fixes: a9471e25629b ("media: hantro: Add core bits to support H264 decoding")
Reported-by: Francois Buergisse
So it matches the code and the spec.

And use it for all native type comparisons, even if it's not strictly
required. By doing that we make the code more consistent and prevent
from potential incorrect results in case of overflow or when the the
values being compared are both negative.

support the new hooks, and vice versa.
Note that the timecode field is gone, since there doesn't seem to be
in-kernel users, but can be added back in the reserved area if needed.

Just a new version of v4l2_fill_mbus_format() to deal with the new
v4l2_ext_pix_format struct.
This is needed to convert the VIMC driver to the EXT_FMT/EXT_BUF iocts.

The rockchip vdec block is a stateless decoder that's able to decode
H264, HEVC and VP9 content. This patch only adds H264 support and is
making use of the m2m codec helpers.
