Subject: [PATCH 2/4] dt-bindings: power: battery: add constant-charge-current-max-microamp property

This adds the constant-charge-current-max-microamp property to the list
of optional properties of the battery.

The constant charge current is critical for batteries as they can't
handle all charge currents.
