    Use broadcast SIPI to startup siblings
    The current code for initializing AP cpus has several shortcomings:
    - it assumes APIC IDs are sequential
    - it uses only the BSP for determining the AP count, which is bad if
      there's more than one physical CPU, and CPUs are of different type
    Note that the new code call cpu->ops->init() in parallel, and therefore
    some CPU code needs to be changed to address that. One example are old
    Intel HT enabled CPUs which can't do microcode update in parallel.
