power: supply: core: rename power_supply_get_by_phandle to power_supply_get_by_reference

(devm_)power_supply_get_by_phandle now internally uses fwnode and are no
longer DT specific. Thus drop the ifdef check for CONFIG_OF and rename
to (devm_)power_supply_get_by_reference to avoid the DT terminology.
