    haswell: allow for disabled hyperthreading
    There were assumptions being made in the haswell
    MP and SMM code which assumed the APIC id space
    was 1:1 w.r.t. cpu number. When hyperthreading is
    disabled the APIC ids of the logical processors
    are all even. That means the APIC id space is sparse.
    Handle this situation.
