Currently the variable timings are supported only for DP and eDP and not for DP MST. Call intel_vrr_compute_config() for MST which will configure fixed refresh rate timings irrespective of whether VRR is supported or not. Since vrr_capable still doesn't have support for DP MST this will be just treated as non VRR case and vrr.vmin/vmax/flipline will be all set to adjusted_mode->crtc_vtotal. This will help to move away from the legacy timing generator and always use VRR timing generator by default.
