Subject: [PATCH] drm: Set non-desktop property to true for writeback and
 virtual connectors

The non-desktop property "Indicates the output should be ignored for
purposes of displaying a standard desktop environment or console."

That sounds like it should be true for all writeback and virtual
connectors as you shouldn't render a desktop to them, so set it
by default.
