David Hildenbrand 73b3294b11 mm: simplify folio_page() and folio_page_idx()
Now that a single folio/compound page can no longer span memory sections
in problematic kernel configurations, we can stop using nth_page() in
folio_page() and folio_page_idx().

While at it, turn both macros into static inline functions and add kernel
doc for folio_page_idx().
