regmap: Add the indexed cache support
This is the simplest form of a cache available in regcache. Any registers whose default value is 0 are ignored. If any of those registers are modified in the future, they will be placed in the cache on demand. The cache layout is essentially using the provided register defaults by the regcache core directly and does not re-map it to another representation.
