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.
