dfu: add partition support for MTD backend
Add the support of MTD partition for the MTD backend.
The expected dfu_alt_info for one alternate on the mtd device :
<name> part <part_id>
<name> partubi <part_id>
"partubi" also erase up to the end of the partition after write operation.
For example: dfu_alt_info = "spl part 1;u-boot part 2; UBI partubi 3"
U-Boot> dfu 0 mtd nand0
