powerpc/hydra: Update MDIO mux fixups

The new device trees use a more generic interface for
supporting muxing mdio buses. The mux property is thus
specified in "reg", rather than "fsl,hydra-mdio-muxval".

In order to support using old device trees, we keep the
old fixup in there. Linux will therefore see the both
properties, but will ignore fsl,hydra-mdio-muxval.
