[Intel-gfx] [PATCH v3 6/7] drm/i915: Init DDI outputs based on port_mask on skl+

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

Instead of listing every platform's possible DDI outputs
in intel_setup_outputs() just loop over the new port_mask
to achieve the same thing.

HSW/BDW were left as is since they still look at the straps
as well.

DSI is still a mess. For now just check for the relevant
platforms explicitly.
