TGL+ should no longer need any VT-d scanout workarounds.
Don't apply any.

Not 100% sure whether pre-SNB might also suffer from this. The
workaround did originate on SNB but who knows if it was just
never caught before that. Not that I ever managed to enable
VT-d any older hardware. Last time I tried on my ILK it ate
the disk!
