drm/i915: honor forced connector modes v2
In the move over to use BIOS connector configs, we lost the ability to
force a specific set of connectors on or off. Try to remedy that by
dropping back to the old behavior if we detect a hard coded connector
config.
v2: don't deref connector state for disabled connectors (Jesse)
