To allow users of the power supply framework to be hw description agnostic, this commit adds the ability to pass a fwnode pointer, via the power_supply_config structure, to the initialisation code of the core, instead of explicitly specifying of_ndoe. If that fwnode pointer is provided then it will automatically resolve down to of_node on platforms which support it, otherwise it will be NULL. In the future, when ACPI support is added, this can be modified to accommodate ACPI without the need to change calling code which already provides the fwnode handle in this manner.
