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. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
