[PATCH] soc: qcom: icc-bwmon: Convert to use maple tree register cache

[wangkaiyuan <wangkaiyuan@inspur.com>]

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.
