From: Pekka Paalanen <pekka.paalanen at collabora.co.uk>
Switch drm_output_find_by_connector() to search for the output by
iterating the compositor's head_list. drm_head_find_by_connector() will
be useful later on its own.
As of "compositor-drm: start migration to head-based output API" the
head list is guaranteed to contain all created drm_outputs through the
automatically created drm_head.
This simplifies the code a little, introduces
drm_head_find_by_connector(), and works towards the eventual removal of
drm_output_find_by_connector().
