Subject: mm: simplify arch_make_folio_accessible()

Patch series "mm: remove arch_make_page_accessible()".
Now that s390x implements arch_make_folio_accessible(), let's convert
remaining users to use arch_make_folio_accessible() instead so we can
remove arch_make_page_accessible().
This patch (of 3):
Now that s390x implements HAVE_ARCH_MAKE_FOLIO_ACCESSIBLE, let's turn
generic arch_make_folio_accessible() into a NOP: there are no other
targets that implement HAVE_ARCH_MAKE_PAGE_ACCESSIBLE but not
HAVE_ARCH_MAKE_FOLIO_ACCESSIBLE.
