[U-Boot] [PATCH] dfu: Migrate to Kconfig

[Lukasz Majewski <l.majewski@samsung.com>]

Hi Tom,

> Introduce a hidden USB_FUNCTION_DFU Kconfig option and select it for
> CMD_DFU (as we must have the DFU command enabled to do anything DFU).
> Make all of the entries in drivers/dfu/Kconfig depend on CMD_DFU and
> add options for all of the back end choices that DFU can make use of.

> Once ack'd I'll run moveconfig.py to migrate everyone over and check
> for size changes.  This will also depend on the patch I sent to
> change the malloc pool size on TI parts as we otherwise will now
> expose the bug about DFU_MMC being unset.
