Further more, the way we express the non-PAS properties in the PAS node
in the dtsi and then switch the compatible in the non-PAS devices means
that we're causing validation errors.

So we should explode this binding to get rid of the conditionals and to
describe the "superset" of the PAS and non-PAS compatibles, for
platforms where this is applicable.
