    Right now rockchip platform need to copy bl31.elf into u-boot
    source directory to make use of building u-boot.itb.
    
    So, add environment variable BL31 like Allwinner SoC so-that the
    bl31.elf would available via BL31.
    
    If the builds are not exporting BL31 env, the make_fit_atf.py
    explicitly create dummy bl31.elf in u-boot root directory to
    satisfy travis builds and it will show the warning on console as
    
     WARNING: BL31 file bl31.elf NOT found, resulting binary is non-functional
     WARNING: Please read Building section in doc/README.rockchip
    
    Note, that the dummy bl31 files were created during not exporting
    BL31 case would be removed via clean target in Makefile.
