skip_ioapic_setup is defined in arch/i386/io_apic.c, which is
conditionally compiled only, if CONFIG_X86_IO_APIC is defined. which is
only defined for SMP or when CONFIG_X86_UP_IOAPIC is set.

init/main.c:332 and arch/i386/kernel/dmi_scan.c:357 do both use it and
don't depend on CONFIG_X86_IO_APIC themselves.
