[PATCH] ppc32: make cur_cpu_spec a single pointer instead of an array
Changed ppc32 so that cur_cpu_spec is just a single pointer for all CPUs.
Additionally, made call_setup_cpu check to see if the cpu_setup pointer
is NULL or not before calling the function. This lets remove the dummy
cpu_setup calls that just return.
