Uh, seems I'm seriously confusing APIC with something else then...

Anyway, if each CPU always has its own APIC there's no reason to link<>
them. It should be a child<> and it should be initialized in-place.

Igor, can you please look into that?

In that case the only open issue would be whether to use cpu_index or
the APIC ID as the property name in this patch.
