Mike Smith 642ba07a24 If we are running in APIC_IO mode, pretend that we didn't see the BIOS
reporting an AT PIC.  We do this because otherwise the PIC will claim
IRQ 2 in an unshareable mode, preventing other devices from legitimately
using it.

For symmetry, in !APIC_IO mode, ignore the APIC if it's reported.

This is a hack; a better solution would have the PIC's driver release
the IRQ if it was not going to be active.
