Subject: ALSA: usb-audio: add quirk flag to enable native DSD for McIntosh devices

From: Max McCarthy <mmccarthy@xxxxxxxxxxxxxxxx>

commit 99248c8902f505ec064cf2b0f74629016f2f4c82 upstream.

McIntosh devices supporting native DSD require the feature to be
explicitly exposed. Add a flag that fixes an issue where DSD audio was
defaulting to DSD over PCM instead of delivering raw DSD data.
