[Intel-gfx] [PATCH 4/9] drm/i915/dvo: Introduce intel_dvo_connector_type()

[Ville Syrjala <ville.syrjala@linux.intel.com>]

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

Introduce intel_dvo_connector_type() as a counterpart to
intel_dvo_encoder_type(), mainly to declutter intel_dvo_init()
a bit.
