Please convert this to regmap. There should be lots of docs and
examples around, for example:

http://elinux.org/images/a/a3/Regmap-_The_Power_of_Subsystems_and_Abstractions.pdf

There is no generic w1 handler, but you can provide custom
read/write functions. Also it would be nice to have this
based on https://lkml.org/lkml/2017/3/16/604. Then everything
could go into the power-supply driver.
