ASoC: Intel: sof-function-topology-lib: add different channel number sdw

dmic support

Now the machine driver provides the sdca dmic channel number information
in the dai link name. We can use the information to select different
topologies for different dmic channels. To be backward compatible, the
2ch sdca dmic topology will still use the "sdca-mic" topology.
