ASoC: rsnd: add support graph base DT phase 2
To enable OF-graph base DT on rsnd driver, and to keep compatible previous normal sound card style, it need to support both "rcar_sound,dai" and "ports" (or "port") on DT. This patch parses both style. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
