devices. Add a $ref to the mfd binding for these devices.

Notes:
This patch is dependent on "dt-bindings: net: Add Realtek MDIO
controller" which adds the realtek,rtl9301-mdio.yaml binding.
Changes in v6:
- Remove realtek,port property
- Remove leftover mdio-controller node.
- Fix some style issues.
- Fuller example including the port to phy-handle mapping
Changes in v5:
- Note dependency on realtek,rtl9301-mdio.yaml patch
- Add back reg property to the mdio-controller node.
Changes in v4:
- There is a single MDIO controller that has MDIO buses as children
Changes in v3:
- None
Changes in v2:
- None
