MLK-16536-12 video: fbdev: dcss: flush cfifo once per frame

Change the cfifo flush to be once per frame to combine
possible multiple flush requests in one frame into one
flush to improve performance. And during one frame, only
flush requests from different channels can be combined,
and the different requests from the same channel cannot
be combined into one flush.
