When the nvmem framework is enabled, a nvmem device is created per mtd device/partition. It is not uncommon that a device can have multiple mtd devices with partitions that have the same name. Eg, when there DT overlay is allowed and the same device with mtd is attached twice. Under that circumstances, the mtd fails to register due to a name duplication on the nvmem framework. With this patch we use the mtdX name instead of the partition name, which is unique.
