drm: add helper to sort panels to the head of the connector list
Userspace seems to like this, see commit cb0953d734348e8862d6d7edc666cfb3bf6d8fae Author: Adam Jackson <ajax@redhat.com> Date: Fri Jul 16 14:46:29 2010 -0400 drm/i915: Initialize LVDS and eDP outputs before anything else This makes them sort to the front in X, which makes them likely to be the primary outputs if you haven't specified a preference in your DE, which is likely to be what you want. Signed-off-by: Adam Jackson <ajax@redhat.com> Signed-off-by: Eric Anholt <eric@anholt.net> Sorting the connector list after the fact is much easier than trying to be clever with the init sequence.
