ALSA: snd-usb-caiaq: Add support for Maschine
This adds partial support for the Maschine controller by Native Instruments. Supported now are the 1x1 MIDI interface and the 41 buttons, 11 endless rotary encoders, and 16 pressure-sensitive drum pads. Still to work on are the dimmable LEDs and the two monochrome screens.
