ALSA: firewire-motu: code refactoring to handle model specific switch for protocol v2
In MOTU FireWire series, devices which support protocol version 2 have
several types of hardware design to process audio data frames for isoc
packet. Roughly devices are categorized into three groups:
- 828mkII
- Traveler/896HD
- UltraLite/8pre FireWire
Some bit flags in register addressed by 0x'ffff'f000'0b14
includes device-specific effects.
This commit cleanups implementation of protocol v2 in this point.
