[PATCH 5.15 051/279] ALSA: usb-audio: Add support for the Pioneer DJM 750MK2 Mixer/Soundcard

From: William Overton <willovertonuk@gmail.com>

[ Upstream commit 6d27788160362a7ee6c0d317636fe4b1ddbe59a7 ]

The kernel already has support for very similar Pioneer djm products
and this work is based on that.

Added device to quirks-table.h and added control info to
mixer_quirks.c.

Tested on my hardware and all working.
