physmap_of: ensure versatile code is reachable
With the newly added physmap_of_versatile code, we get a build error when physmap_of is in a module, because of_flash_probe_versatile is not exported: ERROR: "of_flash_probe_versatile" [drivers/mtd/maps/physmap_of.ko] undefined! This adds the export, and changes the Makefile so that the code is also put into a loadable module rather than built-in when physmap_of itself is a module.
