When the `dfu` command is called from the U-Boot environment,
it now accepts an optional parameter that specifies a timeout (in seconds).
If a DFU connection is not made within that time the `dfu` command exits
(as it would if Ctrl+C was pressed). If the timeout is left empty or being
zero the `dfu` command behaves as it does now.
This is useful for allowing U-Boot to check to see if anything wants to
upload new firmware before continuing to boot.
The patch is based on the commit
