ASoC: audio-graph-card.c: move audio_graph_parse_of()

Current audio-graph-card functions definition are like below

(A)'	static int graph_get_dais_count();

(B)	int audio_graph_parse_of(...)
	{
		...
(A)		ret = graph_get_dais_count();
		...
	}

(A)	static int graph_get_dais_count(...)
	{
		...
	}
(C)

We don't need to have (A)' definition if audio_graph_parse_of() (B) was
defined at (C). This patch moves (B) to (C).
