[PATCH] i386 kexec: allow the kexec on panic support to compile on voyager

This patch removes the foolish assumption that SMP implied local apics.
That assumption is not-true on the Voyager subarch.  This makes that
dependency explicit, and allows the code to build.

What gets disabled is just an optimization to get better crash dumps so the
support should work if there is a kernel that will initialization on the
voyager subarch under those harsh conditions.

Hopefully we can figure out how to initialize apics in init_IRQ and remove
the need to disable io_apics and this dependency.
