Ok clear, what about the generic ethernet-phy-package.yaml?

Idea was to describe common properties there and then specific PHY
package would add every common property with $ref and add their special
ones on top of that. Would that be ok? (similar to the current
implementation with ethernet-phy-package and qcom,qca807x with the only
difference that qcom,qca807x.yaml would also have the compatible set
(currently missing from this RFC)
