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 https://github.com/01org/edison-u-boot/commit/5e966ccc3c65c18c9783741fa04e0c45e021780c by Sebastien Colleur, which has been heavily reworked due to U-Boot changes in the past.
