fwnode_property_get_reference_args ignores nargs when nargs_prop is
non-NULL. So all the existing callers just pass 0 to nargs. Rather than
convert them, I chose to add another function with different defaults.
There are only four callers that pass nargs_prop, so I could just as
easily change the callers instead.
