Not really, the driver is slightly misdesigned and this patches
try to clean this up a bit. I have prepared a v3 branch for the
MVEBU guys to have a look at first.

Short version: Thanks for trying to review this, but I guess your time
would be better spent on a soon to be posted v3.

Long version:
Not having a callback identifies each control as "generic mpp pins",
so by passing a callback we make them "SoC specific" as a preparation
to remove the common "generic mpp" set/get function.
