NAND subsystem is being slightly reworked to store ECC details in separated fields. In future we'll want to add support for more DT properties as specifying every possible setup with a single "nand-ecc-mode" is a pretty bad idea. To allow this let's add a helper that will support something like "nand-ecc-algo" in future. Right now we use it for keeping backward compatibility.
