[RFC PATCH powerpc] make CONFIG_NUMA depends on CONFIG_SMP

[Li Zhong]

I'm not sure whether it makes sense to add this dependency to avoid
CONFI_NUMA && !CONFIG_SMP. 

I want to do this because I saw some build errors on next-tree when
compiling with CONFIG_SMP disabled, and it seems they are caused by some
codes under the CONFIG_NUMA #ifdefs.
