[PATCH] powerpc/mpc8313erdb: fix kernel panic because mdio device is not probed

[Li Yang]

Probe the new mdio node added by b31a1d8b.  Fix kernel panic problem when
gianfar driver wants to get the of_platform_device of that mdio.

Supersede the patch to add "simple-bus" to gianfar node to fix this problem.
