The dsa-port.yaml binding had several references that can be common to all
ethernet ports, not just dsa-specific ones. Break out the generic bindings
to ethernet-switch-port.yaml they can be used by non-dsa drivers.

v1 -> v2
  * Remove accidental addition of
    "$ref: /schemas/net/ethernet-switch-port.yaml" which should be kept
    out of dsa-port so that it doesn't get referenced multiple times
    through both ethernet-switch and dsa-port.

I know this is just copied, but these have no effect on validation. I 
assume what they are meant to be is these are the subset of 
ethernet-controller.yaml which are allowed, but that would only work 
with 'additionalProperties: false'. That wouldn't work because we also 
want to users to extend this with custom properties. What's needed here 
is a list of properties not allowed:

disallowed-prop: false

Or we can just allow anything from ethernet-controller.yaml and drop 
this list.
