I'm a bit confused. Looking at
   Documentation/devicetree/bindings/arm/primecell.yaml
it is done in the same way as this binding.

Whereas, the syscon use a "select:" on top of it. I'm
pretty sure, I've tested it without the select and the
validator picked up the constraints.

Could you elaborate on what is wrong here? Select missing?
