    layerscape: ls1012ardb: only reserve ext4 fs as default firmware.bin
    
    In Device/ls1012ardb IMAGES variable, there are two separate firmware
    references to the same packages, while do mult-job compile, the same package
    build process will arise conflict occasionally. So, only reserve one ext4 fs
    as the default firmware.bin.
