[PATCH] ppc32: cleanup AMCC PPC40x eval boards to support U-Boot

Cleanup PPC40x eval boards (bubinga, walnut and sycamore) to support U-Boot
as bootloader.  The OpenBIOS bd_info struct is not used in the kernel
anymore (only U-Boot now).

uImage (U-Boot) tested on walnut, sycamore and bubinga
zImage (OpenBIOS) tested on sycamore, bubinga and ebony
