drm/todo: add entry about converting to of_drm_find_and_get_bridge()
of_drm_find_bridge() is deprecated, but converting some users is very
complex and should be reasonably doable only after the DRM panel bridge
lifetime rework. Add a TODO to track this.

Convert users of of_drm_find_bridge() to of_drm_find_and_get_bridge()
510
+
---------------------------------------------------------------------

512
+
Taking a struct drm_bridge pointer requires getting a reference and putting
513
+
it after disposing of the pointer. Most functions returning a struct
514
+
drm_bridge pointer already call drm_bridge_get() to increment the refcount
515
+
and their users have been updated to call drm_bridge_put() when
516
+
appropriate. of_drm_find_bridge() does not get a reference and it has been
517
+
deprecated in favor of of_drm_find_and_get_bridge() which does, but some
518
+
users still need to be converted.
