ppc64: segments may be reordered

Instead of fetching data from the segment array, remember the address
when added and find the kernel text from the parsed elf header.

While add_segment (and hence add_buffer) always adds to the end of
the list of segments, it sorts the previous segments before each
allocation.  In some layouts, the device tree or initrd will fit
in a hole below the the kernel.   When that happens, the previus
code mis-patches purgatory and the kexec fails.
