mm: add vm_insert_mixed
vm_insert_mixed will insert either a raw pfn or a refcounted struct page into the page tables, depending on whether vm_normal_page() will return the page or not. With the introduction of the new pte bit, this is now a too tricky for drivers to be doing themselves. filemap_xip uses this in a subsequent patch.
