Current rtd has "num". It sounds/looks like size of rtd or something, but it will be mainly used at snd_pcm_new() as "device index". This naming is confusable. Let's rename it to "id"

Some drivers are using rtd->num, so let's keep it so far, and remove it if all user was switched.

qcom/qdsp6 want to use irregular rtd->id because of its topology. Current code is calculating it at soc_init_pcm_runtime() which calls soc_new_pcm(), and it doesn't save it to rtd->id.

Let's calculate and save it to rtd at snd_soc_add_pcm_runtime() which create rtd and connect related components.

But, this feature should be implemented by using "dai_link" instead of "component". Add FIXME as comment.
