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:

Introduce another layer of validation in the DSA DT schema, and assert
that CPU and DSA ports must have phylink-related properties present.

I've sent this patch separately because at least right now I don't have
a reason to resend the other 4 patches linked above, and this has no
dependency on those.

If I'm reading

https://lore.kernel.org/r/CAL_JsqKZ6cEny_xD8LUMQUR6AQ0q7JKZMmdP-9MUZxzzNxZ3JQ@mail.gmail.com/ (local)

correctly - the warnings are expected but there needs to be a change 
to properties, so CR? (FWIW I'd lean towards allowing it still, even
tho net-next got closed. Assuming v2 can get posted and acked today.)
