ALSA: firewire-motu: add support for MOTU UltraLite-mk3 (FireWire only model)

UltraLite-mk3 was shipped 2008 by MOTU. This model has two lineups;
FireWire-only and FireWire/USB2.0 Hybrid model. Additionally, the latter
has two variants in respect of the type of IEEE 1394 connector; alpha
and beta connector.

This commit adds support for the FireWire-only model, which is already
discontinued.
