ALSA: usb-audio: Add native DSD support for TEAC UD-301

Add native DSD support quirk for TEAC UD-301 DAC,
by adding the PID/VID 0644:804a.

Annotation: This patch should be applied before the "Luxman DA-06" patch set.
Previously, I sent this patch to alsa-dev ML, but the status is "pending". So, I send again.
