This patch converts powerpc to the generic PTDUMP implementation.

Do the same as commit f8f0d0b6fa20 ("mm: ptdump: reduce level numbers
by 1 in note_page()") and add missing p4d level.
This will align powerpc to the users of generic ptdump.

note_page_update_state() doesn't use page_size. Remove it.
Could also be removed to note_page() but as a following patch
will remove all current users of note_page(), just leave it as
is for now.

Thanks
It's possible for kernel threads to pick up SLB preload entries if
they are accessing userspace with kthread_use_mm. If the kthread
later is context switched while using a different mm, when it is
switched back it could preload SLBs belonging to the previous mm.
This could lead to data
