Changes in v3:
- Remove unnecessary change to BCH settings
- Remove ports 5 & 7 from internal switch for now
Changes in v2:
- Properly define mdio mux, internal mdio, external mdio, mii bus
- Now we define usb3 phy as a mdio node connected to internal mdio,
thanks to work done by RafaÅ MiÅecki on the bcm usb3 phy mdio driver
- Define external SW as a mdio-mii node connected to external mdio
