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
