There has been some movement on that front, shall see where it goes

Versioning aside, although that removes a large part of the motivation,
the interface becomes quite nice:
of_property_present(node, "riscv,isa-extension-zicbom")

That also gives us the ability to define what supported vendor
extensions actually mean in a dt-binding, which to me is a big win in
terms of the aforementioned "wild west".
