[PATCH 4/4] ASoC: audio-graph: tidyup dai_name seting timing

[Kuninori Morimoto]

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

audio-graph is using cpus->dai_name / codecs->dai_name
for dailink->name, but cpus->dai_name might be removed
under simple_parse_node() (= asoc_simple_canonicalize_cpu()).

Thus we need to get dai_name before calling simple_parse_node().
This patch fixup it.
To reduce future confusion, this patch follow same style
for similar parts too.

Fixes: 8859f809c7d5813 ("ASoC: audio-graph: add graph_parse_node()")
Fixes: e51237b8d305225 ("ASoC: audio-graph: add graph_link_init()")
