Subject: [PATCH 1/4] leds: lm3601x: Convert 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.
