[Intel-gfx] [PATCH 04/11] drm/i915: Fix FEC pipe A vs. DDI A mixup

[Ville Syrjala]

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

On pre-TGL FEC is a port level feature, not a transcoder
level features, and it's DDI A which doesn't have it, not
trancodere A. Check for the correct thing when determining
whether FEC is supported or not.
