[POWERPC] efika: add phy-handle property for fec_mpc52xx
The new network driver fec_mpc52xx will not work on efika because the firmware does not provide all required properties. http://www.powerdeveloper.org/asset/by-id/46 has a Forth script to create more properties. But only the phy stuff is required to get a working network. This should go into the kernel because its appearently impossible to boot the script via tftp and then load the real boot binary (yaboot or zimage).
