[PATCH net-next 2/4] dt-bindings: net: qcom,ipq9574-ppe: Tighten ethernet port node constraints

[Til Kaiser]

The port node pattern "^ethernet-port@[1-6]+$" also matches multi-digit
unit addresses such as ethernet-port@11, which the reg property does not
allow. Drop the stray '+'.

Also restrict the ethernet-ports object to its declared properties.
Without this, nodes outside the port pattern are accepted through the
generic ethernet-switch schema.
