powerpc/mm/64s: Add _PAGE_KERNEL_ROX
In the past we had a fallback definition for _PAGE_KERNEL_ROX, but we removed that in commit d82fd29c5a8c ("powerpc/mm: Distribute platform specific PAGE and PMD flags and definitions") and added definitions for each MMU family. However we missed adding a definition for 64s, which was not really a bug because it's currently not used. But we'd like to use PAGE_KERNEL_ROX in a future patch so add a definition now.
