Added arch_lmb_reserve to allow arch specific memory regions protection
Each architecture has different ways of determine what regions of memory
might not be valid to get overwritten when we boot. This provides a
hook to allow them to reserve any regions they care about. Currently
only ppc, m68k and sparc need/use this.
