[RFC PATCH 6/7] powerpc: Update the default FIT image to use the correct load/boot addresses

[Michal Simek]

From: John Williams <john.williams at petalogix.com>

The default kernel_fdt.its hard codes zero load/start addresses, but this may
no longer be true.

As we copy the FIT tree descriptor, update these values based on the incoming
ELF payload.
