ASoC: add for_each_link_codecs() macro
ALSA SoC snd_soc_dai_link has snd_soc_dai_link_component array for codecs. To be more readable code, this patch adds new for_each_link_codecs() macro, and replace existing code to it. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
