Do this separately for read and write, there's doubtless going to be
something that has asymmetry.

We may not be able to fit a whole number of values into whatever the
constraint that the bus has is and partial values don't seem like a good
idea.

This is very confusing, regmap already has a concept of stride and this
isn't the same thing.
