dfu: Implementation of target reset after communication with dfu-util's -R switch
This patch extends dfu code to support transmission with -R switch
specified at dfu-util.
When -R is specified, the extra USB_REQ_DFU_DETACH request is sent after
successful data transmission. Then dfu resources are released and reset
command is issued.
