    mxs: fix image generation for I2SE Duckbills
    
    The standard U-Boot boot scripts for Duckbills expect the
    Linux kernel and device tree files installed below /boot
    within the (ext4) root filesystem.
    Also a raw zImage is expected instead of uImage.
    
    Extend the SD card generation accordingly and while at,
    install all possible Duckbill DT blobs there.
