Since none of the users now reference the cache directly we can happily remove the custom cache code and rely on the regmap cache. For simplicity we don't bother with the register defaults tables but instead read the defaults from the device - regmap is capable of doing this, unlike our old cache infrastructure. This saves a lot of code and allows us to cache the device revision information too.
