cpu/intel/common: Move intel_ht_sibling() to common folder
Make intel_ht_sibling() available on all platforms.
Will be used in MP init to only write "Core" MSRs from one thread
on HyperThreading enabled platforms, to prevent race conditions and
resulting #GP if MSRs are written twice or are already locked.
