[What] Vstartup is contrainted by vblank_nom, so adjusting it to include non-adjusted vtotal in its calculation during freesync video means that Vstartup is not changed when vtotal changes. This fixed the flickering + underflow. dc_extended_blank_supported function was removed because extended blank is only relevant to when zstate is supported. The increased vtotal during freesync can be passed to dml regardless of whether extended blank is supported or not, so this function is not needed. Updates were made recently in dml to the calculation of min_dst_y_next_start. Dml input for dcn314 will now always use the newer calculation for min_dst_y_next_start. Dml input for older dcn versions remains untouched. The variable optimized_min_dst_y_next_start is replaced everywhere with min_dst_y_next_start, and the updated dml allows min_dst_y_next_start to increase to an optimized value during freesync video, then return to default when freesync is disengaged. Also removed registry key for controlling extended blank feature.
