DSA switches can fall into one of two categories: switches where all ports
follow standard '(ethernet-)?port' properties, and switches that have
additional properties for the ports.

The scenario where DSA ports are all standardized can be handled by
swtiches with a reference to the new 'dsa.yaml#/$defs/ethernet-ports'.

The scenario where DSA ports require additional properties can reference
'$dsa.yaml#' directly. This will allow switches to reference these standard
defitions of the DSA switch, but add additional properties under the port
nodes.

v3 -> v4
* Rename "$defs/base" to "$defs/ethernet-ports" to avoid implication of a
"base class" and fix commit message accordingly
* Add the following to the common etherent-ports node:
"additionalProperties: false"
"#address-cells" property
"#size-cells" property
* Fix "etherenet-ports@[0-9]+" to correctly be "ethernet-port@[0-9]+"
* Remove unnecessary newline
* Apply changes to mediatek,mt7530.yaml that were previously in a separate patch
* Add Reviewed and Acked tags

v3
* New patch

This shouldn't be moved. Please reread our conversation on the previous
version.

I see - I missed your point. My apologies. This binding should keep the
reg properties where they were. I'll wait a few more days for any
additional feedback.

Feel free to add my acked-by with the next version.
