ALSA: usb-audio: Add support for Pioneer DJ DDJ-RR controller 



This patch allows the Pioneer DJ DDJ-RR to be seen as a USB audio
device under Linux and therefore usable in such applications as
Mixxx.

Tested Master Audio out, headphones (both output jacks) and microphone
input. All work perfectly.
