x86: X86_HT always enable on X86_64 SMP
X86_HT is used for hyperthreading or multicore on 32-bit. The X86_HT on 64-bit is different from 32-bit, it means hyperthreading only. And X86_HT is not used on 64-bit except from cpu/initel_cacheinfo.c. Unify X86_HT for hyperthreading or multicore. Turn X86_HT on when X86_64 and SMP are enabled.
