I see this is already the case for the aw88261 driver but it is a bit
weird that _REG_MAX isn't the maximum register - it looks like it should
probably be _NUM_REG.  Not the end of the world though.

This looks like debug code which can hopefully be removed in favour of
the regmap implementation?

You should just be able to pass these arrays in the component strucutre?
