ALSA: usb-audio: Add Pioneer DJ DJM-250MK2 quirk
[ Upstream commit 73d8c94084
]
Pioneer DJ DJM-250MK2 is a mixer that acts like a USB sound card.
The MIDI controller part is standard but the PCM part is "vendor specific".
Output is enabled by this quirk: 8 channels, 48 000 Hz, S24_3LE.
Input is not working.

* PCM is 8 channels out @ 48 fixed (endpoints 0x01).

* The output from computer to the mixer is usable.

|

* The input (phono or line to computer) is not working.
|

* It should be at endpoint 0x82 and probably also 8 channels,

* but it seems that it works only with Pioneer proprietary software.
|

* Even on officially supported OS, the Audacity was unable to record
|
||||
* and Mixxx to recognize the control vinyls.
