DFU: Support re-flashing of DFU via DFU
As we re-locate the entire sam7dfu program into RAM, we don't need
to execute from flash and can thus re-program the DFU partition
via the DFU protocol itself (alternate setting '1').
We also implement downloading executable code into RAM using
alternate setting '2'. The latter part is not properly executed yet.
