Since we have two PMICs here, but can not use the 'reg' property (as the
addressing is based on software, i.e. the ACPM firmware), I've opted
for 'pmic' (existing) and 'pmic2' (new) as nodenames.

Maybe 'pmic-main' and 'pmic-sub' would be more appropriate, but 'pmic' is a
bit more standard I believe. I'm open for better suggestions :-) 

Cheers,
