Ian Campbell aa462abe8a mm: fix __page_to_pfn for a const struct page argument ...

This allows the cast in lowmem_page_address (introduced as a warning
fixup to 33dd4e0ec9 "mm: make some struct page's const") to be
removed.

Propagate const'ness to page_to_section() as well since it is required
by __page_to_pfn.
