drm/i915/alpm: Disable LOBF around transitioning for LRR/seamless MN
When enabling LRR/seamless MN disable LOBF first and re-enable
afterwards.
- pre_plane_update: if LOBF was enabled, disable LOBF before the
update_lrr/update_m_n transition.
- post_plane_update: Re-enable LOBF after the transition.
