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 60463628c9e0 ("x86/mm: Implement native set_memory_rox()")
and commit 22e99fa56443 ("s390/mm: implement set_memory_rox()") for
more information.
