Mark of the Unicorn (MOTU) shipped 896HD 2003 as one of models in second
generation of its FireWire series, and already discontinued it. The model
consists of below ICs:
* Texas Instruments TSB41AB2
* Phillips Semiconductors PDI1394L40
* Altera cyclone EP1C3
* Texas Instruments TMS320VC5402
It supports sampling transmission frequency up to 192.0 kHz. The packet
format differs depending on both of sampling transfer frequency and enabling
ADAT channels. The model doesn't support MIDI message transmission.
This commit adds support for it.
