drm/i915/lrr: Include SCL in lrr_params_changed()

Browse source

If SCL is changing we need to take the LRR codepath to update
it during a fastset. Account for that in lrr_params_changed().

The current code will only notice the SCL change if the position
of the delayed vblank also changes. But that might not happen
when using the VRR timing generator because the delayed vblank
is then defined by the guardband instead of the SCL.
