Generate automatically dfu_alt_info for the supported device.
The simple command "dfu 0" allows to start the dfu stack on usb 0
for the supported devices:
- dfu mtd for nand0
- dfu mtd for nor0
- dfu mmc for SDCard
- dfu mmc for eMMC
- dfu ram for images in DDR

The DUF alternate use the "part", "partubi" and "mmcpart" options
to select the correct MTD or GPT partition or the eMMC hw boot partition.
