[PATCH] ALSA: usb-audio: Add DSD quirk for LEAK Stereo 230

[PATCH] ALSA: usb-audio: Add DSD quirk for LEAK Stereo 230

[i.v.zhaldak]

From: Ivan Zhaldak <i.v.zhaldak@gmail.com>

Integrated amplifier LEAK Stereo 230 by IAG Limited has built-in
ESS9038Q2M DAC served by XMOS controller. It supports both DSD Native
and DSD-over-PCM (DoP) operational modes. But it doesn't work properly
by default and tries DSD-to-PCM conversion. USB quirks below allow it
to operate as designed.
 
Add DSD_RAW quirk flag for IAG Limited devices (vendor ID 0x2622)
Add DSD format quirk for LEAK Stereo 230 (USB ID 0x2622:0x0061)
