-Required properties:
-- compatible: "maxim,max8903" for MAX8903 Battery Charger
-- dok-gpios: Valid DC power has been detected (active low, input), optional if uok-gpios is provided
-- uok-gpios: Valid USB power has been detected (active low, input), optional if dok-gpios is provided
-
-Optional properties:
-- cen-gpios: Charge enable pin (active low, output)
-- chg-gpios: Charger status pin (active low, input)
-- flt-gpios: Fault pin (active low, output)
-- dcm-gpios: Current limit mode setting (DC=1 or USB=0, output)
-- usus-gpios: USB suspend pin (active high, output)
