Bindings for SoCs (and by extension boards with them) usually go to in
$arch/$vendor.yaml not into soc/$vendor/$vendor.yaml. Why is this any
different?

You don't actually list any boards here, but instead permit having only
the SoC compatible and no board one. The SoC compatible is also
incredibly generic. Personally I don't think this binding makes any
sense as it appears to exist as a catch all for anything using your
new cores in any combination.
