device property: fwnode_property_read_string_array() returns nr of strings
Functionally fwnode_property_read_string_array() should match of_property_read_string_array() and work as a drop-in substitute for the latter. of_property_read_string_array() returns the number of strings read if the target string pointer array is non-NULL. Make fwnode_property_read_string_array() do the same.
