msm_fb: display: add stage commit before kickoff to WFD

Since stage commit had been splited out of stage up fucnction,
it needed to be called to stage pipes into mixer befroe
kickoff mixer. Add this function into overlay writeback for WFD.
This patch varies a little bit from the mainline patch as it got
updated again. Now making it equivalent to mainline.

msm: display: add mutex for display driver entries

In some cases, display driver is called by multiple threads, this
will cause re-entrance problem. For example, one thread is
calling display commit, the other turns off the display. In order
to serialize the operation, mutex is added to most APIs.
Only the ones for initialization won't be added.
