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

From: Takashi Sakamoto <[email protected]>

[ Upstream commit 13e005f9f933a35b5e55c9d36f151efe2a8383ec ]

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.
