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 Rafa? Mi?ecki on the bcm usb3 phy mdio driver
 - Define external SW as a mdio-mii node connected to external mdio
