[PATCH] mfd: twl6040: Use maple tree register cache

[Mark Brown]

The twl6040 is only capable of performing single register read and write
operations which means it gains no advantage from using a rbtree register
cache, convert it to using the more modern maple tree register cache
instead. This should be more efficient.
