Subject: [PATCH v1 net-next 5/7] 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.

+description:
+  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.
