[why] When we enter FREESYNC_STATE_VIDEO, we want to use the extra vblank portion to enter zstate if possible. [how] When we enter freesync, a full update is triggered and the new vtotal with extra lines is passed to dml in a stream update. The time gained from extra vblank lines is calculated in microseconds. We allow zstate entry if the time gained is greater than 5 ms, which is the current policy. Furthermore, an optimized value for min_dst_y_next_start is calculated and written to its register. When exiting freesync, another full update is triggered and default values are restored.
