disp: msm: sde: compute timeouts based on refresh rate

Browse Source 
Current timeout values in sde driver for vblank, kickoff and
frame complete timeouts are fixed and can be much lower than
a vsync incase of low refresh rate display. Compute timeouts
based on refresh rate for low refresh rate displays.
