MLK-16242-6 video: fbdev: dcss: refine cfifo synchronization logic

Remove the synchronization workaround in 'commit_to_fifo()'
and add ctxld wq flush calls in pan display, since the pan
display usually requires blocking mode behavior. But other
functions can also work in non-blocking mode, so perform
synchronization handling in 'commit_to_fifo' is not good
for the interfaces which doesn't require blocking mode.
