[POWERPC] Cleanup pseries kexec code
Move all the pseries kexec code into one file, platforms/pseries/kexec.c Provide helpers for setting up ppc_md.kexec_cpu_down, so that we don't have to have #ifdef CONFIG_KEXEC in setup.c Move the initialisation of the ppc_md kexec callbacks into an init routine. This is well and truly early enough to cause no change in behaviour, we can't kexec until userspace has given us a kernel to kexec into.
