drm/todo: Add entry to remove load/unload hooks
They're midlayer, broken, and because of the old gunk, we can't fix them. For examples see the various checks in drm_mode_object.c against dev->registered, which cannot be enforced if the driver still uses the load hook. Unfortunately our biggest driver still uses load/unload, so this would be really great to get fixed.

+Remove load/unload callbacks from all non-DRIVER_LEGACY drivers
+---------------------------------------------------------------
+
+The load/unload callbacks in struct &drm_driver are very much midlayers, plus
+for historical reasons they get the ordering wrong (and we can't fix that)
+between setting up the &drm_driver structure and calling drm_dev_register().
+
+- Rework drivers to no longer use the load/unload callbacks, directly coding the
+ load/unload sequence into the driver's probe function.
+
+- Once all non-DRIVER_LEGACY drivers are converted, disallow the load/unload
+ callbacks for all modern drivers.
