[alsa-devel] [PATCH 19/39] fireworks: Add skelton for Fireworks based devices

This commit adds a new driver with no functionality. This driver just
creates/removes card instance according to callbacks.
Fireworks is a board module which Echo Audio produced. This module consists
of three chipsets:
- Communication chipset for IEEE1394 PHY/Link and IEC 61883-1/6
- DSP or/and FPGA for signal processing
- Flash Memory to store firmwares
Current supported devices:
- Mackie Onyx 400F/1200F
- Echo AudioFire12/8(until 2009 July)
- Echo AudioFire2/4/Pre8/8(since 2009 July)
- Echo Fireworks 8/HDMI
- Gibson Robot Interface pack/GoldTop
