The FIELDPIC_FLAG_E bit should be set when field_pic_flag exists in stream,
it is currently set based on field_pic_flag of current frame.
The PIC_FIELDMODE_E bit is correctly set based on the field_pic_flag.
Fix this by setting the FIELDPIC_FLAG_E bit when frame_mbs_only is not set.

A decoded 8-bit 4:2:0 frame need memory for up to 448 bytes per
macroblock with additional 32 bytes on multi-core variants.
Memory layout is as follow:
+---------------------------+
| Y-plane 256 bytes x MBs |
+---------------------------+
| UV-plane 128 bytes x MBs |
+---------------------------+
| MV buffer 64 bytes x MBs |
+---------------------------+
| MC sync 32 bytes |
+---------------------------+
Reduce the extra space allocated now that motion vector buffer offset no
longer is based on the extra space.
Only allocate extra space for 64 bytes x MBs of motion vector buffer
and 32 bytes for multi-core sync.

A decoded 8-bit 4:2:0 frame need memory for up to 448 bytes per

+---------------------------+
| Y-plane 256 bytes x MBs |
+---------------------------+
| UV-plane 128 bytes x MBs |
+---------------------------+
| MV buffer 64 bytes x MBs |
+---------------------------+
The motion vector buffer offset is currently correct for 4:2:0 because
the extra space for motion vectors is overallocated with an extra
64 bytes x MBs.
Wrong offset for both destination and motion vector buffer are used
for the bottom field of field encoded content, wrong offset is
also used for 4:0:0 (monochrome) content.
Fix this by setting the motion vector address to the expected 384 bytes
x MBs offset for 4:2:0 and 256 bytes x MBs offset for 4:0:0 content.
Also use correct destination and motion vector buffer offset
for the bottom field of field encoded content.
While at it also extend the check for 4:0:0 (monochrome) to include an
additional check for High Profile (100).

Commit 953aaa1492c53 ("media: rockchip/vpu: Prepare things to support decoders")
changed the conditions under S_FMT was allowed for OUTPUT
CAPTURE buffers.
However, and according to the mem-to-mem stateless decoder specification,
in order to support dynamic resolution changes, S_FMT should be allowed
even if OUTPUT buffers have been allocated.
Relax decoder S_FMT restrictions on OUTPUT buffers, allowing a
resolution modification, provided the pixel format stays the same.
Tested on RK3288 platforms using ChromiumOS Video Decode/Encode
Accelerator Unittests.

The picture order count table only makes sense for profiles
higher than Baseline. This is confirmed by the H.264 specification
(See 8.2.1 Decoding process for picture order count), which
clarifies how POC are used for features not present in Baseline.
"""
Picture order counts are used to determine initial picture orderings
for reference pictures in the decoding of B slices, to represent picture
order differences between frames or fields for motion vector derivation
in temporal direct mode, for implicit mode weighted prediction in B slices,
and for decoder conformance checking.
"""
As a side note, this change matches various vendors downstream codebases,
including ChromiumOS and IMX VPU libraries.

The setting of the motion vectors usage and the setting of motion
vectors address are currently done under different conditions.
When decoding pre-recorded videos, this results of leaving the motion
vectors address unset, resulting in faulty memory accesses. Fix it
by using the same condition everywhere, which matches the profiles
that support motion vectors.
