MTD already allocates backing_dev_info dynamically. Convert it to use generic infrastructure for this including proper refcounting. We drop mtd->backing_dev_info as its only use was to pass mtd_bdi pointer from one file into another and if we wanted to keep that in a clean way, we'd have to make mtd hold and drop bdi reference as needed which seems pointless for passing one global pointer...
