The power-supply framework has the notion of one power-supply device being supplied by another. A typical example of this is a charger charging a battery. A tablet getting plugged in to charge (or plugged out) only results in events seen by the axp288_charger device / MFD cell. Which means that a change udev-event only gets send for the charger power-supply class device, not for the battery (the axp288_fuel_gauge device). The axp288_fuel_gauge does have an external_power_change'd callback which will generate a change udev-event when called. But before this commit this never got called because the power-supply core only calls this when a power-supply class device's supplier changes and the supplier link from axp288_charger to axp288_fuel_gauge was missing. Add a "supplied-from" property to axp288_fuel_gauge cell, pointing to the "axp288_charger" power-supply class device, so that the axp288_fuel_gauge's external_power_change'd callback gets called on axp288_charger state changes.
