[PATCH 11/13] drm/i915/display: Update intel_crtc_vrr_{enable/disable}

[Ankit Nautiyal]

With CMRR the vrr.enable was tracking the vrr timing generator, which made
the helpers intel_crtc_vrr_{enable/disable} also track the
vrr timing generator.
Since we don not have CMRR now, the crtc_vrr_{enable/disable} should now
track the vrr mode of operation of the vrr timing generator.

Update the helpers intel_crtc_vrr_{enable/disable} to track the vrr mode
of the vrr timing generator.
