ALSA: usb-audio: Add Pioneer DJ DJM-V10 support

Pioneer DJ DJM-V10 is a high end mixer that acts like a USB sound card.
The MIDI controller part is standard but the PCM part is "vendor specific".
Input and output is enabled by this patch:
  - 12 channels (6 stereo) in each direction
  - 44 100 / 48 000 / 96 000 Hz
  - S24_3LE

Capture channels can be configured through alsamixer.
Playback channels are fixed and controlled by hardware knobs on the mixer.
