device property: Introduce fwnode_property_get_reference_args
The new fwnode_property_get_reference_args() interface amends the fwnode property API with the functionality of both of_parse_phandle_with_args() and __acpi_node_get_property_reference(). The semantics is slightly different: the cells property is ignored on ACPI as the number of arguments can be explicitly obtained from the firmware interface.
