ACPI: properties: Align return codes of __acpi_node_get_property_reference()

acpi_fwnode_get_reference_args(), the function implementing ACPI
support for fwnode_property_get_reference_args(), returns directly
error codes from __acpi_node_get_property_reference(). The latter
uses different error codes than the OF implementation. In particular,
the OF implementation uses -ENOENT to indicate that the property is
not found, a reference entry is empty and there are no more
references.

Document and align the error codes for property for
fwnode_property_get_reference_args() so that they match with
of_parse_phandle_with_args().

Fixes: 3e3119d3088f (device property: Introduce fwnode_property_get_reference_args)
