[PATCH v4 0/3] drm: remove deprecated *_of_get_bridge() from non-OF drivers

[Luca Ceresoli]

Replace the deprecated *_of_get_bridge() calls with
of_drm_get_bridge_by_endpoint() for all drivers which can be built without
CONFIG_OF.

Some of those drivers had a build failure for configs without
CONFIG_OF. This series used have fixes for those failures plus other
patches to convert all other such drivers to
of_drm_get_bridge_by_endpoint().

All the fixes are already applied, so since v3 there are only the
improvement patches not yet applied.
