smp, generic: introduce arch_disable_smp_support() instead of disable_ioapic_setup()
Impact: cleanup disable_ioapic_setup() in init/main.c is ugly as the function is x86-specific. The #ifdef inline prototype there is ugly too. Replace it with a generic arch_disable_smp_support() function - which has a weak alias for non-x86 architectures and for non-ioapic x86 builds. Signed-off-by: Ingo Molnar <mingo@elte.hu>
