ALSA: firewire-motu: add support for MOTU Track 16

Mark of the Unicorn designed Track 16 2011 as one of models in third
generation of its FireWire series. The model is already discontinued.
It consists of below ICs:

 * Texas Instruments TSB41AB1
 * Microchip (SMSC) USB3300
 * Xilinx Spartan-3A FPGA, XC3S700A
 * Texas Instruments TMS320C6722
 * Microchip (Atmel) AT91SAM SAM7S512

It supports sampling transfer frequency up to 192.0 kHz. The packet
format differs depending on both of current sampling transfer frequency
and the type of signal in optical interfaces. 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.
