simple-card is supporting dai-link support, but simple-scu-card doesn't have it. This patch support it. This is prepare for merging simple-card and simple-scu-card.

In DPCM case, it uses CPU-dummy / dummy-Codec dai links. If sound card is caring only DPCM, link count = dai count, but, if non DPCM case, link count != dai count. Now, we want to merge simple-card and simple-scu-card, then, we need to care both link / dai count more carefly This patch cares it, and prepare for merging simple card

In DPCM case, it uses CPU-dummy / dummy-Codec dai links, and non DPCM case, it uses CPU-Codec dai links.

Now, we want to merge simple-card and simple-scu-card.

These sound cards are using silimar but not same logic on each functions. Then, of course we want to share same logic. To compromise, this patch uses cpu/codec pointer on simple-scu-card. It is same logic with simple-card, thus easy merging. This is prepare for merging simple card
