linux-yocto/meta: smp: Add config X86_BIGSMP since its needed when NR_CPUS > 8

Updating the kernel meta data with the following configuration change:

  When we set NR_CPUS to something > than 8, we also need to set
  X86_BIGSMP
  according to Kconfig:

  config X86_BIGSMP
        bool "Support for big SMP systems with more than 8 CPUs"

  otherwise NR_CPU will end up being reset to 8
