Subject: [PATCH] ALSA: usb-audio: Add DSD support for Gustard U16/X26 USB

For 5.3 and 4.19 I took the following as dependencies:
eb7505d52a2f ("ALSA: usb-audio: DSD auto-detection for Playback Designs")
0067e154b11e ("ALSA: usb-audio: Update DSD support quirks for Oppo and Rotel")
For older kernels it was becoming too long of a list, and I don't have a
way to test it so I didn't do anything about it there. Backports are
more than welcome.
Note: yes, patching it up to apply on 4.14 is easy, but if this patch is
needed there then there are quite a few more needed so I didn't want to
take just this one.
