    i386/lapic: Handle the case that the CPU does not have LAPIC for SMP kernel
    
    If LAPIC does not exist:
    - Reset apic_io_enable and reinitialize ICU if necessary; mainly for
      ICU's auto EOI setting.
    - Setup minimum information for BSP's globaldata
    
    While I'm here, add hw.lapic_enable tunable to test this feature (just don't
    use it :).
