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".
