I need to look more into this. The compatible string should remain
mscc,vsc7514-switch, but I think the pattern properties should
probably be updated to "^(ethernet-)switch@[0-9a-f]+$" to match
ethernet-switch.yaml.

I didn't think the ethernet-switch.yaml could be at the top level for
the 7514, but I must have been mistaken. Either way - not under
compatible as you're pointing out. Much appreciated.
