Now that we properly set the physical address in the program header of the
vmlinux ELF we can extract it to properly set the load and entry point for
u-boot uImages. Before we always hard coded the laod & entry point to 0.
However there are situations that the kernel may be built with a non-zero
physical address.
We use objdump to extract the PHDR. We assume that there is only one
PHDR in the vmlinux of type LOAD.
