dd5ac03e09 powerpc/mm: Fix page table dump build on non-Book3S
In the recent commit 1515ab9321 ("powerpc/mm: Dump hash table") we
added code to dump the hage page table. Currently this can be selected
to build on any platform. However it breaks the build if we're building
for a non-Book3S platform, because none of the hash page table related
defines and so on exist. So restrict it to building only on Book3S.

Similarly in commit 8eb07b1870 ("powerpc/mm: Dump linux pagetables")
we added code to dump the Linux page tables, which uses some constants
which are only defined on Book3S - so guard those with an #ifdef.

Useful to be able to dump the kernels page tables to check permissions
and memory types - derived from arm64's implementation.

Add a debugfs file to check the page tables. To use this the PPC_PTDUMP
config option must be selected.
