Subject: [PATCH v2 net-next 4/6] dt-bindings: net: add generic ethernet-switch

The dsa.yaml bindings had references that can apply to non-dsa switches. To
prevent duplication of this information, keep the dsa-specific information
inside dsa.yaml and move the remaining generic information to the newly
created ethernet-switch.yaml.

Signed-off-by: Colin Foster <colin.foster@...advantage.com>
Suggested-by: Vladimir Oltean <olteanv@...il.com>
---

v1 -> v2
  * No net change, but deletions from dsa.yaml included the changes for
    "addionalProperties: true" under ports and "unevaluatedProperties:
    true" under port.

+  This binding represents Ethernet Switches which have a dedicated CPU
+  port. That port is usually connected to an Ethernet Controller of the
+  SoC. Such setups are typical for embedded devices.
