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.

Use get_frame_desc() to get the frame desc from the connected source,
and use the provided virtual channel and datatype instead of hardcoded
ones.
get_frame_desc() can contain multiple streams, but as we don't support
multiple streams yet, we will just always use the first stream.
If the source doesn't support get_frame_desc(), fall back to the
previous method of always capturing virtual channel 0 and any datatype.

The AWB workqueue runs in a kernel thread and needs to be synchronized
w.r.t. the streaming status.
It is possible that streaming is stopped while the AWB workq is running.
In this case it is likely that the check for vb2_start_streaming_called is
done at one point in time, but the AWB computations are done later,
including a call to isc_update_profile, which requires streaming to be
started.
Thus , isc_update_profile will fail if during this operation sequence the
streaming was stopped.
To solve this issue, a mutex is added, that will serialize the awb work and
streaming stopping, with the mention that either streaming is stopped
completely including termination of the last frame is done, and after that
the AWB work can check stream status and stop; either first AWB work is
completed and after that the streaming can stop correctly.
The awb spin lock cannot be used since this spinlock is taken in the same
context and using it in the stop streaming will result in a recursion BUG.

During experiments with libcamera, it looks like vb2_is_streaming returns
true before our start streaming is called.
Order of operations is streamon -> queue -> start_streaming
ISC would have started the DMA immediately when a buffer is being added
to the vbqueue if the queue is streaming.
It is more safe to start the DMA after the start streaming of the driver is
called.
Thus, even if vb2queue is streaming, add the buffer to the dma queue of the
driver instead of actually starting the DMA process, if the start streaming
has not been called yet.
Tho achieve this, we have to use vb2_start_streaming_called instead of
vb2_is_streaming.

The vertical subsampling factor is currently not considered in the
offset calculation for plane cropping done in rpf_configure_partition.
This causes a distortion (shift of the color plane) when formats with
the vsub factor larger than 1 are used (e.g. NV12, see
vsp1_video_formats in vsp1_pipe.c). This commit considers vsub factor
for all planes except plane 0 (luminance).
Drop generalization of the offset calculation to reduce the binary size.

hdl->error was set, and if so, v4l2_ctrl_handler_free is called and

For some invalid frames,
especially multiple consecutive invalid frames,
they all can't be decoded,
then the firmware can send picture skipped event
to notify driver that some frames are invalid,
driver can return them with error flag.

copy the timestamp using the helper function
V4L2_BUF_FLAG_TIMESTAMP_COPY
To implement this, driver will keep the output buffer until it's
encoded, in previous, driver will return the output buffer immediately
after firmware return it
