Extends the MTD configdata device with the following features / additions:
1. Configurable option to use named config items instead of enumerated ID/Instance numbers. 2. Ability to iterate through the existing configdata items in the /dev/config device. 3. Ability to "unset" a configdata item. 4. Ability to perform "flash_eraseall" on the /dev/config device.
