powerpc/thp: tracing: Hide hugepage events under CONFIG_PPC_BOOK3S_64

The events hugepage_set_pmd, hugepage_set_pud, hugepage_update_pmd and
hugepage_update_pud are only called when CONFIG_PPC_BOOK3S_64 is defined.
As each event can take up to 5K regardless if they are used or not, it's
best not to define them when they are not used. Add #ifdef around these
events when they are not used.
