ASoC: SDCA: Add helper to add DAI constraints
Currently the core SDCA code simply creates a place holder available
channels from 1 to SDCA_MAX_CHANNEL_COUNT. Add a helper function
that will constrain the number of channels based on the actual
available SDCA Clusters in DisCo. Currently this code only handles
Input Terminal Entities as they directly specify the Cluster. More
work will be required later for Output Terminals which inherit their
Cluster. Typically this new helper would be called from the DAIs
startup callback.
