[PATCH 1/2] drm/i915: Disable port sync when bigjoiner is used

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

The current modeset sequence can't handle port sync and bigjoiner
at the same time. Refuse port sync when bigjoiner is needed,
at least until we fix the modeset sequence.
