Subject: regmap: Initialize `map->debugfs' before regcache

regmap: Initialize `map->debugfs' before regcache

In the rbtree code we are exposing statistics relating to the
number of nodes/registers of the rbtree cache for each of the
devices.  Ensure that `map->debugfs' has been initialized before
we attempt to initialize the debugfs entry for the rbtree cache.
