    mvebu: fix missing property in puzzle thermal
    
    Fix missing property in puzzle thermal. The thing was never supposed to
    work.
    
    Property #thermal-sensor-cells was missing from the puzzle hwmon, making
    the entire thermal platform referencing that fail to probe with -EINVAL.
    
    The puzzle hwmon expose 2 termistor but they probably use an userspace
    downstream utility to configure and handle thermal. For this reason we
    really don't know what they use the sensor for or when it's attached.
    
    We use them to sensor if the Chassis gets too hot due to ambient
    temperature and generic components getting too warm.
