of_graph: add of_graph_get_port_parent()
Linux kernel already has of_graph_get_remote_port_parent(), but, sometimes we want to get own port parent. This patch adds of_graph_get_port_parent() Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>
