Subject: [PATCH 12/75] drm/i915: don't setup hdmi for port D edp in ddi_init

3.8.13.6 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Daniel Vetter <daniel.vetter@...ll.ch>

commit 21a8e6a4853b2ed39fa4c5188a710f2cf1b92026 upstream.

dp_init_connector adjusts the encoder type if it is a eDP panel. Use
that to decide whether we should set up a hdmi connector or not.

To do so reorder the hdmi connector setup sequence in ddi_init a bit.
