On the theory that it's better to make a start let's add some KUnit tests for regmap. Currently this is a bit of a mess but it passes and hopefully will at some point help catch problems. We provide very basic cover for most of the core functionality that operates at the register level, repeating each test for each cache type in order to exercise the caches. There is no coverage of anything to do with the bulk operations at the bus level or formatting for byte stream buses yet. Each test creates it's own regmap since the cache structures are built incrementally, meaning we gain coverage from the different access patterns, and some of the tests cover different init scenarios.
