x86: move apicid mappings to smpboot.c 



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

 * FIXME: For x86_64, those are defined in other files. But moving them here,

 * 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

 * right now, they'll stay here -- glommer
