lantiq: dts: assign the MDIO pins to the gsw node

Assign the MDIO pins to the switch node instead of using pin hogging
(where pins are assigned to the pin controller).
This is the preferred way of assigning pins upstream.

This converts amazonse, ar9 and vr9. danube is skipped because the pin
controller doesn't define a pinmux for the MDIO pins (some of the SoC
pads may be hardwired to the MDIO pins instead of being configurable).
