[PATCH 20/29] drm/i915: Don't use encoder->type in intel_ddi_set_pipe_settings()

[Ville Syrjala <ville.syrjala@xxxxxxxxxxxxxxx>]

From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

encoder->type isn't reliable for DP/HDMI so instead extract the correct
type from the crtc state in intel_ddi_set_pipe_settings().
