power: supply: Add fwnode pointer to power_supply_config struct
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.
