[PATCH 4/5] ASoC: SDCA: Add missing function type names

[Charles Keepax <ckeepax@opensource.cirrus.com>]

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.
