[Intel-gfx] [PATCH] drm/i915: Extract intel_encoder_has_connectors()

[ville.syrjala at linux.intel.com]

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

We have an open coded loop which tries to see if the encoder has any
connectors linked to it. Let's extract that to a helper similar to
intel_crtc_has_encoders().
