pcr: libreboot-utils: armv7h: skip remaining tools requiring port mapped I/O
    
    The warning about bucts was removed as in fact most of these tools are
    probably dangerous in one way or another if used improperly.
    
    Flashrom which is packaged in most GNU/Linux distributions is also very
    dangerous if used improperly, though it comes with warnings and safe
    defaults.
