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

audio-graph is using cpus->dai_name / codecs->dai_name for
dailink->name.
In graph_parse_node(), xxx->dai_name is got by
snd_soc_get_dai_name(), but it might be removed soon by
asoc_simple_canonicalize_cpu().

The order should be
	*1) call snd_soc_get_dai_name()
	 2) create dailink name
	*3) call asoc_simple_canonicalize_cpu()

* are implemented in graph_parse_node().
This patch remove 3) from graph_parse_node()
