ppc4xx: Add fdt support to all remaining AMCC PPC4xx eval boards

This patch adds fdt (flattened device tree) support to all remaining AMCC
eval boards. Most newer boards already support device tree. With this patch,
all AMCC boards now enable device tree passing from U-Boot to Linux
arch/powerpc kernels.
