Yes, it's always fine to use a rbtree if it makes sense - it was just an unusual choice for a device like this that didn't seem to be discussed.
Depending on the register map a flat cache can actually be more memory efficient sometimes since there's some overhead for the rbtree data structures, if you've just got one block of registers with no gaps a flat cache is going to be a win there.
