When client queued a buffer, v4l2 framework
compares the client Dmabuf with the existing
dmabuf in the bufs array at the same index.
If the dmabuf is different then v4l2 framework
would call unmap_dmabuf, detach_dmabuf callbacks
for the old buffer and then calls attach_dmabuf,
map_dmabuf callbacks for the new buffer before
qbuf callback is made to driver. If the dmabuf
is same then qbuf callback will be made directly.
V4l2 framework expects that clients recycles the
same buffers in the same indices so that when
v4l2 framework compares dmabuf it won't unmap
or map buffers.
If client recycle the buffers in different indices
still usecase works but there will be unnecessary
unmap, map overhead will be incurred.
If client does not recycle the buffers at all,
meaning every time client queues new buffers
then special handling is required for decoder
output buffers which are used for reference by
video hardware.If any buffers are used by video
hardware as reference buffers then firmware returns
those buffers with READ_ONLY flag and they are kept
in read_only list and when read_only grows beyond
some limit then driver would ask firmware to release
those READ_ONLY buffers and when firmware responds
driver would delete these READ_ONLY buffers.

Flushed out buffers by driver retain filled length field same
as it was while queued to driver. This is incorrect as it
gives an impression to the client that some data has been
written by driver/firmware. Hence, reset this to 0 while
dequeuing to fix the issue.

interface queues were allocated only once and reused for entire
lifetime, but un-consumed packets in the queue during sys_error
is leading to undefined behaviour for the next session.
For e.x, after queueing cmd_init, received sys_error, so core
will be deinited and sys_init willbe sent again as part of next
session_open, but FW is consuming 1st cmd_init pkt and sending
init_done but driver is expecting done for 2nd cmd_init, So
i.e treated as fatal and driver is closing the session and
doing core_deinit.
To avoid above mentioned issue, made changes to reset queue hdr
incase of sys_error.

Video driver has a logic to vote for maximum power resources for
initial few frames. If any video session remains within those
initial few frames, the votes calculated would reflect as maximum.
To handle such video sessions, there is another logic to check
if the video session has any input buffer to process. If there
are no input buffers to process for that session, there is no
need to consider that session for power resource voting. Hence
skip the votes aggregation for such sessions during concurrency.
