powerpc/pgtable: remove _PAGE_BIT_SWAP_TYPE for book3s
The swap type is simply stored in bits 0x1f of the swap pte. Let's
simplify by just getting rid of _PAGE_BIT_SWAP_TYPE. It's not like that
we can simply change it: _PAGE_SWP_SOFT_DIRTY would suddenly fall into
_RPAGE_RSV1, which isn't possible and would make the
BUILD_BUG_ON(_PAGE_HPTEFLAGS & _PAGE_SWP_SOFT_DIRTY) angry.
While at it, make it clearer which bit we're actually using for
_PAGE_SWP_SOFT_DIRTY by just using the proper define and introduce and use
SWP_TYPE_MASK.
