msm_fb: display: vsync driven screen update

This patch will queue multiple 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 delivered to the user space frame work via uevent. Both
queue and commit are controlled by frame work and synchonized
with vsync event. Therefore frame rate will match with vsync rate.
