drm/i915/vrr: Disable VRR when using bigjoiner
commit dcd8992e47f13afb5c11a61e8d9c141c35e23751 upstream.
All joined pipes share the same transcoder/timing generator.
Currently we just do the commits per-pipe, which doesn't really
work if we need to change switch between non-VRR and VRR timings
generators on the fly, or even when sending the push to the
transcoder. For now just disable VRR when bigjoiner is needed.
