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. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
