Alesis MasterControl was shipped 2009 and already discontinued. This model
consists of:
* TSB41AB2 for physical layer of IEEE 1394
* WaveFront Dice II STD for link layer and protocol implementation
* FreeScale DSPB56374AE
Although the firmware of this model can respond against read transaction
to address space for TCAT extension protocol, the content is not valid
for protocol extension. This results in sound card without any PCM/MIDI
interfaces.

This commit adds support the model by adding hard-coded stream formats.
