Since it is not a DAX-specific function, move it into mm and rename it

FYI, there is a patch in -mm and linux-next:
"mm: rmap: introduce pfn_mkclean_range() to cleans PTEs"
that adds a vma_pgoff_address which seems like a bit of a superset of
the one added in this patch, but only is in mm/internal.h.
Yes. The function in this patch handles more cases.
So, let me rebase onto this patch and move the function into
/include/linux/mm.h, so that fs/dax.c can also use it. Is this ok?
