ALSA: dice: add support for Lexicon I-ONIX FW810s

I-ONIX FW810s was shipped in Lexicon brand of HARMAN International
industries, Inc 2009. The model uses TCD2220 ASIC as its communication
engine. TCAT general protocol is supported, its extension isn't.

This patch adds support for the model with hard-coded stream formats.
