Are global exports preferred over the callbacks? I saw both in different
MFD drivers and was not sure which one to use.

I've selected callbacks, because they are a bit nicer and don't pollute
the name space for each single driver. In my opinion the cost of these
3 max8998_reg_{read,write,update} inline functions in regulator/max8998.c
is not so significant.
