ALSA: fireface: code refactoring to add enumeration constants for model identification
In RME fireface series, version field of unit directory in configuration ROM is used to distinguish each model. The value of field is known and it's better to use enumeration constants for code representation. This commit adds enumeration constants for model identification.
