Subject: hda-codec: make mixemu selectable at runtime

Define PARAM so that we have two versions of the "desc_codec
and family" structs. Add a property called "mixer" whose default
value depends on whether CONFIG_MIXEMU is defined or not which
will help us call the appropriate instance init functions.
