The fimc_md_parse_port_node() function return 0 if an endpoint node is
not found but according to Documentation/devicetree/bindings/graph.txt,
a port must always have at least one enpoint.
So return an -EINVAL errno code to the caller instead, so it knows that
the port node parse failed due an invalid Device Tree description.
