mm: make the __PAGETABLE_PxD_FOLDED defines non-empty
[ Upstream commit a8874e7e8a8896f2b6c641f4b8e2473eafd35204 ]
Change the currently empty defines for __PAGETABLE_PMD_FOLDED,
__PAGETABLE_PUD_FOLDED and __PAGETABLE_P4D_FOLDED to return 1.
This makes it possible to use __is_defined() to test if the
preprocessor define exists.
