msm_fb: display: vsync driven screen update

This patch will queue multiply surfaces and commit those
surfaces into mdp at same instance so that surfaces will
be blended and displayed at same time. Hardware vsync event
is deliver to frame work at user space via uevent. Both
queue and commit are controlled by frame work and
synchonized with vsync event. Therefore frame rate will
match with vsync rate.
