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 :).
