It is desirable that new DSA drivers are written to expect that all their ports register with phylink, and not rely on the DSA core's workarounds to skip this process. To that end, DSA is being changed to warn existing drivers when such DT blobs are in use, and to opt new drivers out of the workarounds. Introduce another layer of validation in the DSA DT schema, and assert that CPU and DSA ports must have phylink-related properties present.
