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.
