powerpc/64s: Fix CONFIG_NUMA=n build due to create_section_mapping()

Browse source

With CONFIG_NUMA=n the build fails with:

  arch/powerpc/mm/book3s64/pgtable.c:275:15: error: no previous prototype for ‘create_section_mapping’ [-Werror=missing-prototypes]
  275 | int __meminit create_section_mapping(unsigned long start, unsigned long end,
      |               ^~~~~~~~~~~~~~~~~~~~~~

That happens because the prototype for create_section_mapping() is in
asm/mmzone.h, but asm/mmzone.h is only included by linux/mmzone.h
when CONFIG_NUMA=y.

In fact the prototype is only needed by arch/powerpc/mm code, so move
the prototype into arch/powerpc/mm/mmu_decl.h, which also fixes the
build error.
