[PATCH] Clean up and refactor i386 sub-architecture setup

Clean up and refactor i386 sub-architecture setup.

This change moves all the code from the
asm-i386/mach-*/setup_arch_pre/post.h headers, into
arch/i386/mach-*/setup.c.  mach-*/setup_arch_pre.h is renamed to
setup_arch.h, and contains only things which should be in header files.  It
is purely code-motion; there should be no functional changes at all.

Several functions in arch/i386/kernel/setup.c needed to be made non-static
so that they're visible to the code in mach-*/setup.c.  asm-i386/setup.h is
used to hold the prototypes for these functions.
