ALSA: firewire-digi00x: add support for console models of Digi00x series

Browse Source 
Digi00x series includes two types of unit; rack and console. As long as
reading information on config rom of Digi 002 console, 'MODEL_ID' field
has a different value from the one on Digi 002 rack.

We've already got a test report from users with Digi 003 rack. We can
assume that console type and rack type has different value in the field.

This commit adds a device entry for console type. For following commits,
this commit also adds a member to 'struct snd_digi00x' to identify console
type.
