[POWERPC] mpc82xx: Remove a bunch of cruft that duplicates generic functionality.
m82xx_calibrate_decr(), mpc82xx_ads_show_cpuinfo(), and mpc82xx_halt() do anything useful beyond what the generic code does. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
