Christophe Leroy 09ca1b1171 powerpc: Implement set_memory_rox() ...

Same as x86 and s390, add set_memory_rox() to avoid doing
one pass with set_memory_ro() and a second pass with set_memory_x().

See commit 60463628c9 ("x86/mm: Implement native set_memory_rox()")
and commit 22e99fa564 ("s390/mm: implement set_memory_rox()") for
more information.
