ALSA: firewire-motu: add support for MOTU Traveler mk3

Mark of the Unicorn (MOTU) shipped Traveler mk3 as one of models in third
generation of its FireWire series, and discontinued it already. The model
consists of below ICs:

 * Texas Instruments TSB41AB2
 * Phillips Semiconductors PDI1394L40
 * Altera cyclone EP1C3
 * Texas Instruments TMS320VC5402

It supports sampling transfer frequency up to 192.0 kHz. The packet
format differs depending on both of current sampling transfer frequency
and whether to enable ADAT channels in rx/tx packets. The model supports
transmission of PCM frames as well as MIDI messages.

The model supports command mechanism to configure internal DSP. Hardware
meter information is available in the first 2 chunks of each data block
of tx packet.

This commit adds support for it.
