arch/x86/ioapic: Select IOAPIC with SMP

For coreboot proper, I/O APIC programming is not really required,
except for the APIC ID field. We generally do not guard the related
set_ioapic_id() or setup_ioapic() calls with CONFIG(IOAPIC).
In practice it's something one cannot leave unselected, but maintain
the Kconfig for the time being.
