drm/i915: Validate that the timings are within the VRR range

Browse source

Let's assume there are some crazy displays where the high
end of the VRR range ends up being lower than the refresh
rate as determined by the actual timings. In that case
when we toggle VRR on/off we would step outside the VRR
range when toggling VRR on/off. Let's just make sure that
never happens by not using VRR in such cases. If the user
really wants VRR they should then select the timings to
land within the VRR range.
