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 subunit are a bit different.
