[PATCH v2 08/12] ASoC: simple-card-utils: add simple_props_to_xxx() macro

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

We shouldn't use dai_props->cpus/codecs/cpu_dai/codec_dai/codec_conf
directly, because these are array to supporting multi CPU/Codec/Platform.
This patch adds asoc_link_to_xxx() macro for it.
