ASoC: audio-graph-card2.c: make Codec2Codec settings optional
Current audio-graph-card2 can use Codec2Codec, and having its original parameter (= rate) on DT is mandatory for now. But simple-card-utils.c has asoc_simple_init_for_codec2codec() to setup *default* Codec2Codec settings. This patch makes Audio Graph Card2 Codec2Codec rate settings optional.
