Current ASoC CPU:Codec = N:M connection is using connection mapping idea, but it is used for CPU < Codec case only. We want to use it for any case.

By this patch, not only N:M connection, but all existing connection (1:1, 1:N, N:N) will use same connection mapping. Because it will use default mapping, no conversion patch is needed to exising CPU/Codec drivers.

More over, CPU:Codec = M:N (M > N) also supported in the same time.

Now ASoC is supporting CPU/Codec = N:M connection. This patch adds its sample settings.

But 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.
