ASoC: audio-graph-card2-custom-sample: add CPU/Codec = N:M sample

Now ASoC is supporting CPU/Codec = N:M connection, add its sample
settings.

One note here is that it has many type of samples, it reached to
maximum of sound minor number. Therefore, new sample is disabled so far.
If you want to try it, you need to disable some other one instead.
