[PATCH] x86-64/i386: Don't process APICs/IO-APICs in ACPI when APIC is disabled.

When nolapic was passed or the local APIC was disabled
for another reason ACPI would still parse the IO-APICs
until these were explicitely disabled with noapic.

Usually this resulted in a non booting configuration unless
"nolapic noapic" was used.

I also disabled the local APIC parsing in this case, although
that's only cosmetic (suppresses a few printks)

This hopefully makes nolapic work in all cases.
