mpc83xx: convert to using do_fixup_*()
convert to using simpler mpc85xx style fdt update code; streamline by eliminating macros OF_SOC, OF_CPU, etc. which allows us to rm the old school FLAT_TREE code from 83xx (since the sbc8349 was just converted over to using libfdt). Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
