Subject: [PATCH 0/3] net: dsa: b53: mmap: add MDIO Mux bus controller

B53 MMAP devices have a MDIO Mux bus controller that must be registered after
properly initializing the switch.
If the MDIO Mux controller is registered from a separate driver and the device
has an external switch present, it will cause a race condition which will hang
the device.
