msm: camera: Add support for concurrent ISP
For concurrent ISP operation, a single camera image is
split and feed into two ISP. Each ISP will process
the image independently and output to different location in
one single buffer. This change add support to synchronize
the buffer used in each ISP. When the first ISP dequeue
a buffer, the buffer will be store in a separate queue.
The second ISP will first check the intermediate queue
and then check the main queue for buffer. When ISP is done
processing the image, the buffer will be send out only
when both ISPs are done with the buffer.
