Some drivers are retrieving the nand_chip pointer using the container_of macro on a struct wrapping both the nand_chip and the mtd_info struct while the standard way of retrieving this pointer is through mtd->priv. Provide an helper to do that.

Pushed this patch to l2-mtd.git, though I rebased it directly onto 4.4-rc1 and then merged it in. That way, if any other subsystems want to start using this in the 4.5 -next cycle (e.g., for patches 4-8), they can pull it in without taking the rest of MTD. I can push this to a separate branch or signed tag, if anyone wants. Or, I can take the arch/ patches via MTD, if that's a better option. Brian
