Max Filippov 25384ce5f9 xtensa: SMP: limit number of possible CPUs by NR_CPUS 
This fixes the following warning at boot when the kernel is booted on a
board with more CPU cores than was configured in NR_CPUS:

  smp_init_cpus: Core Count = 8
  smp_init_cpus: Core Id = 0
  ------------[ cut here ]------------
