And roll them out across drm_* files. The point here isn't code prettification (it helps with that too) but that some of these lists aren't static any more. And having macros will gives us a convenient place to put locking checks into.
I didn't add an iterator for props since that's only used by a list_for_each_entry_safe in the driver teardown code.
Search&replace was done with the below cocci spatch. Note that there's a bunch more places that didn't match and which would need some manual changes, but I've intentially left these out for this mostly automated patch.
