disp: msm: sde: program the start window based on "EPT_FPS"

Parcourir la source 
Introduce a new connector property called “EPT_FPS” for the cmd
mode panels. User space will set the “EPT_FPS” based on the
intended content fps, relative to the last retire fence timestamp
as calculated by Surface flinger. Program start window based
on the Expected Present Time fps.
