fdt: Fix fdt padding issue for initrd mem_rsv
Its possible that we end up with a device tree that happens to be a
particular size that after we call fdt_resize() we don't have any
space left for the initrd mem_rsv.
Fix this be adding a second mem_rsv into the size calculation. We
had one to cover the fdt itself and we have the potential of adding
a second for the initrd.
