powerpc/mm/64s: Move THP reqs into a separate symbol
Move the Kconfig symbols related to transparent hugepages (THP) under a
separate config symbol, separate from CONFIG_PPC_BOOK3S_64.
The new symbol is automatically enabled if CONFIG_PPC_BOOK3S_64 is
enabled, so there is no behaviour change, except for the existence of
the new PPC_THP symbol.
