erofs: enable large folios for iomap mode
Enable large folios for iomap mode. Then the readahead routine will
pass down large folios containing multiple pages.
Let's enable this for non-compressed format for now, until the
compression part supports large folios later.
When large folios supported, the iomap routine will allocate iomap_page
for each large folio and thus we need iomap_release_folio() and
iomap_invalidate_folio() to free iomap_page when these folios get
reclaimed or invalidated.
