simple-card / audio-graph are assuming single CPU/Codec/Platform on dai_link. Because of it, it is difficult to support Multi-CPU/Codec.
This patch allocs CPU/Codec/Platform dai_link imformation instead of using existing props information. It can update to multi-CPU/Codec, but is still assuming single-CPU/Codec for now.
