ALSA: bebob: Add skelton for BeBoB based devices
This commit adds a new driver for BeBoB based devices with no specific
operations. Currently this driver just create/remove card instance according
to callbacks.
BeBoB is 'BridgeCo enhanced Breakout Box'. This is installed to firewire
devices with DM1000/DM1100/DM1500 chipset. It gives common way for host
system to handle BeBoB based devices.
Current supported devices:
- Edirol FA-66/FA-101
- PreSonus FIREBOX/FIREPOD/FP10/Inspire1394
- BridgeCo RDAudio1/Audio5
- Mackie Onyx 1220/1620/1640 (Firewire I/O Card)
- Mackie d.2 (Firewire Option)
- Stanton FinalScratch 2 (ScratchAmp)
- Tascam IF-FW DM
- Behringer XENIX UFX 1204/1604
- Behringer Digital Mixer X32 series (X-UF Card)
- Apogee Rosetta 200/Rosetta 400 (X-FireWire card)
- Apogee DA-16X/AD-16X/DD-16X (X-FireWire card)
- Apogee Ensemble
- ESI Quotafire610
- AcousticReality eARMasterOne
- CME MatrixKFW
- Phonix Helix Board 12 MkII/18 MkII/24 MkII
- Phonic Helix Board 12 Universal/18 Universal/24 Universal
- Lynx Aurora 8/16 (LT-FW)
- ICON FireXon
- PrismSound Orpheus/ADA-8XR
Devices possible to be supported if identifying IDs:
- Apogee Mini-Me Firewire/Mini-DAC Firewire
- Behringer F-Control Audio 610/1616
- Cakewalk Sonar Power Studio 66
- CME UF400e
- ESI Quotafire XL
- Infrasonic DewX/Windy6
