From: Dimitri Fedrau <dimitri.fedrau@xxxxxxxxxxxx>
With DT properties charge-current-limit-gpios and
charge-current-limit-mapping one can define charge current limits in uA
using up to 32 GPIOs. Add property charge-current-limit-default-microamp
which selects a default charge current limit that must be listed in
charge-current-limit-mapping.
