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.

v5 -> v6
  * Minor change to fix conflict with the removal of "Device Tree
    Binding" in the title line

v4 -> v5
  * Add Rob Reviewed tag
  * Change Vivien to Vladimir to match MAINTAINERS
  * Capitalize all words in title line (Generic DSA Switch Port)
  * Add better description of an Ethernet switch port

v3 -> v4
  * Add Florian Reviewed tag

v2 -> v3
  * Change dsa-port title from "DSA Switch port Device Tree Bindings"
    to "Generic DSA Switch port"
  * Add reference to ethernet-switch-port.yaml# in dsa-port.yaml
  * Change title of ethernet-switch-port.yaml from "Ethernet Switch
    port Device Tree Bindings" to "Generic Ethernet Switch port"
  * Remove most properties from ethernet-switch-port.yaml. They're
    all in ethernet-controller, and are all allowed.
  * ethernet-switch.yaml now only references ethernet-switch-port.yaml#
    under the port node.

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.

Still doesn't look too great that the ethernet-switch-port description
is this thing devoid of meaning. What is said about the dsa-port is what
the description should be here, and the description of the dsa-port is
that it's a generic Ethernet switch port plus DSA specific properties.

Also, I see your patches are deferred in patchwork, and while this isn't
really for me to say, presumably it's because there was no announcement
so far that net-next reopened.

Apologies - you mentioned this earlier as well. I'm not sure how I
missed it in v5 (and therefore v6)

Based on above, it might be for the better.
