Add a device tree node for the MDIO controller on the RTL9300 chips.

Notes:
    This was originally part of a series adding the bindings and the
    driver[1]. These were split off and have now been applied via net-next.
    That just leaves the dts changes to come in via linux-mips.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]
