[PATCH] sound: add quirk flag to enable native DSD for McIntosh devices

["McCarthy, Max" <mmccarthy@xxxxxxxxxxxxxxxx>]

From: Max McCarthy <mmccarthy@xxxxxxxxxxxxxxxx>

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.
