x86: move apicid mappings to smpboot.c

Browse Source 
They are i386 specific (the x86_64 definitions live
elsewhere, and should remain there), so are enclosed around
an ifdef

* would make the setup areas dependent on smp, which is a loss. When we
* integrate apic between arches, we can probably do a better job, but
