Cover letter [PATCH 0/6 v5] Introduce caching support for regmap

This patch series introduces register caching support for regmap. I've mostly implemented all the suggestions, except the use of a dedicated init function for each of the compress types.

The only change since v4 is that I've renamed all instances of cache_defaults' to reg_defaults'.

Some things have been left out, such as support for bulk read operations, various optimizations, shared caches etc.
Most of this stuff will be implemented incrementally.

This version has only been build tested, so any testing would be highly appreciated. The changes though since v3 are trivial so it should work.

Thanks to Lars-Peter Clausen and Mark Brown for all the constructive comments.
