The same comment I made last time applies now: this isn't something that
should be being handled at the driver level.
For all your I/O functions there's not really any work going on in the
function except the translation from struct da9052 to the regmap it
points to. May as well just turn the functions into inlines.

If you hit an error you didn't handle an IRQ and so ought to be
returning IRQ_NONE.
