x86: make the LAPIC / IOAPIC construct switchable with Kconfig

There are still systems running which do not have any LAPIC or even
IOAPIC. Responsible MSRs for those do not exist and the systems are
crashing on trying to setup LAPIC.

This commit makes the APIC stuff able to switch off for those boards
which dont' have an LAPIC / IOAPIC.
