fdt: Add fdt_translate_address to convert reg node to cpu phys addr
This code is extracted out of the Linux Kernel code from
arch/powerpc/kernel/prom_parse.c.
We maintain some of the same structure to support multiple bus types even
though we only have one in the current code. In the future we might want
to translate across a PCI bus and thus it will be easier to add that
functionality back in.
