[PATCH] ALSA: usb-audio: add mixer quirks for Pioneer DJM-900NXS2

[Fabian Lesniak]

This patch is based upon Olivia's patch "ALSA: usb-audio: Add DJM750 to 
Pioneer mixer quirk" and applies cleanly after that one on v5.11-rc6. If 
Olivia improves the original patch, I will send this one again as well.

If there is some means to express such dependencies between patches, I'm sorry 
for not doing so.

Cheers
Fabian
