Define CONFIG_SPF for BOOK3S_64 and SMP. This enables the Speculative Page
Fault handler.
Support is only provide for BOOK3S_64 currently because:
- require CONFIG_PPC_STD_MMU because checks done in
set_access_flags_filter()
- require BOOK3S because we can't support for book3e_hugetlb_preload()
called by update_mmu_cache()
