msm_fb: Fix the hang issues due to improper usage of vsync

For LCDC/DSI command/DTV interfaces, fix the various corner cases
of wait4vsync getting stuck due to TG turned off/wait4sync
count being reset to zero etc. Add timeout to waiting for vsync
to avoid hang issues when vsync interrupt is turned off.
