[U-Boot] [RFC] Another DFU implementation

[Stefan Schmidt]

Hello.

This patch is not meant for merging yet. I'm sending it here to allow
Andrzej and other having a look at this implementation. The end goal would be to
merge both DFU implementations with a split between DFU implementation and
different flashing backends.

Architectural comments are really welcome here. Coding style and implementation
details are likely to change.

regards
Stefan Schmidt
