Subject: [PATCH net-next v6 1/6] dt-bindings: mfd: Add switch to RTL9300

Add bindings for the ethernet-switch portion of the RTL9300.

Notes:
    Changes in v6:
    - New
    - I'd like to enforce the property being "ethernet-ports" but I see the
      generic binding allows "ports" as well. Can I just add ethernet-ports:
      type: object here or does by driver need to handle both "ports" and
      "ethernet-ports" (I see some do and some don't).
