Yes, we need to parse it one way or another. dev->is_thunderbolt is
based on heuristics which do not apply anymore when the thing gets
integrated in the SoC.

The _DSD is there already (on existing systems) and is being used by
Windows so I don't understand why we cannot take advantage of it? Every
new system with Thunderbolt ports will have it.
