ASoC: SDCA: Add missing function type names

It is not helpful to error out on some SDCA function types, we
might as well report the correct name and let the driver core
simply not bind a driver to those functions for which the code
lacks support. Also given no functions currently have support,
it seems odd to select some as unsupported.
