mfd: axp20x: Update to use maple tree register cache 



The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.

Update the axp20x driver to use the more modern data structure, really it
should have been fine even without the most recent round of updates.
