We have introduced CONFIG_NUMA in previous patch. And this
option is enabled only on x86 in current stage. In a follow
up patch, we will enable this option for Arm. But we still
want users can disable the CONFIG_NUMA through Kconfig. In
this case, keep current fake NUMA API, will make Arm code
still can work with NUMA aware memory allocation and scheduler.
