MIPS: SMP: Do not initialize __cpu_number_map/__cpu_logical_map for CPU 0. 

A system isn't necessarily booted on physical processor 0 as this code
assumes.  Also the array happens to be allocated in .bss so it's zero
initialized anyway.  Systems which need to override this can do so in
their mp_ops->smp_setup() method.
