[PATCH 11/16] ASoC: soc-core: add new soc_link_init()

[Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>]

From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

Current soc_probe_link_dais() (1) is called under probe_order (2),
and it will initialize dai_link related settings at *Last* turn (3)(B).
It is very complex code.

	static int soc_probe_link_dais(..., order)
	{
(A)		/* probe DAIs here */
		...

(3)		if (order != SND_SOC_COMP_ORDER_LAST)
			return 0;

(B)		/* initialize dai_link related settings */
		...
	}

	static int snd_soc_instantiate_card(...)
	{
		...
(2)		for_each_comp_order(order) {
			for_each_card_rtds(...) {
(1)				ret = soc_probe_link_dais(..., order);
			}
		}
	}

This patch separes soc_probe_link_dais() into "DAI probe" portion (A),
and dai_link settings portion (B).
The later is named as soc_link_init() by this patch.
