[PATCH] powerpc: Define 'crash_kexec_wait_realmode' for Non-SMPsystems.

[Shaun Ruffell]

This fixes a regression from b987812b3fcaf70fdf0037589e5d2f5f2453e6ce
"powerpc/kexec: Fix mismatched ifdefs for PPC64/SMP" which resulted in

arch/powerpc/kernel/crash.c: In function âdefault_machine_crash_shutdownâ:
  arch/powerpc/kernel/crash.c:349: error: implicit declaration of function
  âcrash_kexec_wait_realmodeâ

message on when compiling on Blue&White G3 and CONFIG_SMP is not defined.
