Define DSA port binding per switch model as each switch model requires
different values for certain properties.

Define reg property on $defs as it's the same for all switch models.

Remove unnecessary lines as they are already included from the referred
dsa.yaml.

Again, I don't understand why do you remove definitions of these nodes
from top-level properties. I explained what I expect in previous
discussion and I am confused to hear "this cannot be done".

I agree it can be done, but the binding is done with less lines the 
current way.

I would need to add more lines than just for creating the node structure 
since dsa.yaml is not referred.

Then, I would have to create the node structure again for the dsa-port 
checks.

I understand you can create binding more concise, but not necessarily
more readable. The easiest to grasp is to define all the nodes in
top-level and customize them in allOf:if:then. This was actually also
needed for earlier dtschema with additionalProperties:false. You keep
defining properties in allOf:if:then, even though they are all
applicable to all variants. That's unusual and even if it reduces the
lines does not make it easier to grasp.
