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

ASoC is using many lists.
Now, used dai_link is listed to card as dai_link_list.

	[card]->[dai_link]->[dai_link]->...

This "dai_link" is used to create "rtd".
And this rtd is listed to card as rtd_list.

	[card]->[rtd]->[rtd]->...

Here, each rtd has dai_link. This means, we can track all dai_link via
rtd list. This patch removes card dai_link_list, and uses rtd_list
instead of it.
