ALSA: bebob: Add support for Yamaha GO series

This commit allows this driver to support all of models which Yamaha produced
with DM1000/BeBoB. They are:
 - GO44
 - GO46

This commit adds Yamaha specific operations. To get source of clock, AV/C Audio
Subunit command is used.

I note that their appearances are similar to some models of TerraTec; 'Go44' is
similar to 'PHASE 24 FW' and 'GO46' is similar to 'PHASE X24 FW'. But their
combination of Audio/Music subunits is a bit different.

* Yamaha GO44 is not designed to be used as stand-alone mixer. So any streams
* must be accompanied. If changing the state, a LED on the device starts to
* blink and its sync status is false. In this state, the device sounds nothing
* even if streaming. To start streaming at the current sampling rate is only
* way to revocer this state. GO46 is better for stand-alone mixer.
* Both of them have a capability to change its sampling rate up to 192.0kHz.
* At 192.0kHz, the device reports 4 PCM-in, 1 MIDI-in, 6 PCM-out, 1 MIDI-out.
* But Yamaha's driver reduce 2 PCM-in, 1 MIDI-in, 2 PCM-out, 1 MIDI-out to use
* 'Extended Stream Format Information Command - Single Request' in 'Additional
* AVC commands' defined by BridgeCo.
* This ALSA driver don't do this because a bit tiresome. Then isochronous
* streaming with many asynchronous transactions brings sounds with noises.
* Unfortunately current 'ffado-mixer' generated many asynchronous transaction
* to observe device's state, mainly check cmp connection and signal format. I
* reccomend users to close ffado-mixer at 192.0kHz if mixer is needless.
