ASoC is using many lists. Now, used dai_link is listed to card as dai_link_list.
[card]->[dai_link]->[dai_link]->...
BTW, 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.
