This will introduce a ton of warnings in .dts files which I don't think
anyone wants to go fix.
While I think it's redundant to have the c22 (or c45) fallback as it
isn't really useful on its own, I think we are too far down that path.
You need a custom 'select' in all the schemas that have a c22
compatible to exclude it from matching.
