The "Project" column on bspec #33450 does list EHL, however I don't see
it actually listed on the dedicated EHL WA page (bspec #33451) or the
TGL WA page (bspec #52890).
I'm not sure which page we're supposed to trust for EHL (personally I'd
trust the EHL page more than the ICL page when it comes to EHL), but it
doesn't look like this should apply to TGL/gen12 as far as I can see?
