As there are some registers missing which are required for future charger

I have something in preparation for the power supply driver, but I am
sending this now if this might go in earlier e.g. via  BD72720 
immutable branch to avoid more immutable branches.
@Matti: Can you check the situation with the other chips supported
by that driver. Is that register there, too?
