If your driver is a good candidate for rbtree it's a good candidate for
maple tree.  There are very few specialist cases where there's an
advantage to sticking with rbtree.  The maple cache has no meaningful
overhead compared to rbtree for non-sparse regmaps and will generate
bulk writes just fine.
