powerpc/mm: drop #ifdef CONFIG_MMU in is_ioremap_addr()

powerpc always selects CONFIG_MMU and CONFIG_MMU is not checked
anywhere else in powerpc code.

Drop the #ifdef and the alternative part of is_ioremap_addr()

Fixes: 9bd3bb67 ("mm/nvdimm: add is_ioremap_addr and use that to check ioremap address")
