MTL is the only platform where we've enabled multiple GTs at the moment
(one primary, one media). Although multi-tile platforms could
potentially have more, we haven't enabled multi-tile on i915 for xehpsdv
and pvc, and will probably refocus that work on the Xe driver now. So
reducing to 2 sounds fine.
