From: Aric Cyr <aric....@amd.com> [why] There is only a single call to dc_post_update_surfaces_to_stream so there is no need to have two flags to control it. Unifying this to a single flag allows dc_stream_adjust_vmin_vmax to skip actual programming when there is no change required.
[how] Remove wm_optimze_required flag and set only optimize_required in its place. Then in dc_stream_adjust_vmin_vmax, check that the stream timing range matches the requested one and skip programming if they are equal.
