Subject: [PATCH v2 0/2] power: supply: add charger for BD71828

Add basic charger which does just read out simple registers without
doing any sophisticated things. 

This is a stripped down version of
https://lore.kernel.org/lkml/dbd97c1b0d715aa35a8b4d79741e433d97c562aa.1637061794.git.matti.vaittinen@fi.rohmeurope.com/

That version includes all the bells-and-whistles you might imagine
around coloumb counter handling and capacity measurement which includes
changes no the power supply core.
Rather do a step by step approach to keep that reviewable.
