Firmware might hold the DPB buffers for reference in case of sequence
change, so skip destroying buffers for which QUEUED flag is not removed.

The decoder is stopped after it completes the dynamic resolution change
sequence. Handle VIDIOC_STREAMOFF() and VIDIOC_STREAMON() on the CAPTURE
queue to resume the decoding process.

Implement the vb2 ops for the buf queue. These are the different buffer
attributes:
BUF_ATTR_DEFERRED - buffer queued by the client but not submitted to
firmware.
BUF_ATTR_PENDING_RELEASE - buffers requested to be released from
the firmware.
BUF_ATTR_QUEUED - buffers submitted to the firmware.
BUF_ATTR_DEQUEUED - buffers received from the firmware.
BUF_ATTR_BUFFER_DONE - buffers sent back to vb2.
