mfd: adp5585: Refactor how regmap defaults are handled
The only thing changing between variants is the regmap default
registers. Hence, instead of having a regmap configuration for every
variant (duplicating lots of fields), add a chip info type of structure
with a regmap ID to identify which defaults to use and populate
regmap_config at runtime given a template plus the id. Also note that
between variants, the defaults can be the same which means the chip info
structure can be used in more than one compatible.
This will also make it simpler adding new chips with more variants.
Also note that the chip info structures are deliberately not const as
they will also contain lots of members that are the same between the
different devices variants and so we will fill those at runtime.
