bebob: Add support for M-Audio Firewire series which uses special firmware

This commit allows this driver to support some models which M-Audio produces
with DM1000/BeBoB but its firmware is special. They are:
 - Firewire 1814
 - ProjectMix I/O

Firewire1814 and ProjectMix I/O has BeBoB firmware but it's heavily customized.
The usual operations given by BeBoB aren't be applied for them. For this reason,

specific functions and control interface.

This commit adds M-Audio specific operations, quirks. They are categorized to
