powerpc: Fix ioremap_flags() with book3e pte definition
We can't just clear the user read permission in book3e pte, because
that will also clear supervisor read permission. This surely isn't
desired. Fix the problem by adding the supervisor read back.
BenH: Slightly simplified the ifdef and applied to ppc64 too
