[PATCH 1/3] mfd: max77620: Convert to use maple tree register cache

[Mark Brown]

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.
