[PATCH 10/22] drm/i915/dp_mst: Use VRR Timing generator for DP MST for fixed_rr

[Ankit Nautiyal]

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.
