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.

Early HT-enabled CPUs do not serialize microcode updates within a core.
Solve this by running microcode updates on the thread with the smallest
lapic ID of a core only.
Also set MTRRs once per core only.
