The benefit is deduplication of a lot of code. You may consider it the same as
GPIO library does with IRQ chip. This is just the same on a different level.

Besides the driver in this series, I would think of other GPIO drivers that
are not (yet) converted to regmap (partially because of this is being absent)
or existing drivers, if any, that may utilise it.
