powerpc/kdump: Disable ftrace during kexec
We should disable ftrace during kexec, some of the tracers are very invasive
and we do not want them going off while doing the low level work of swapping
one kernel out for another. This mirrors what we do on x86.
Even though we cannot return from a kexec on powerpc (since we do not implement
CONFIG_KEXEC_JUMP), add the restore code in case we do one day.
