Add possibility to define a part of partition as a separate DFU entity. This allows to have more than one items on the given partiton.
The real use case for this option is TM2 board. It can use u-boot stored as Linux kernel on the defined partiton (as RAW data) and load the real kernel from the same partition, but stored under the certain offset.
