Re: add phy-handle property for fec_mpc52xx

Woo!  Thanks Olaf.  I was just about to sit down and write something
like this myself.  Looks good to me.  I'll pick this up (but I'm going
to move it to the fixup_device_tree_efika() function)

Cheers,
g.

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).
