    hwmon: (lm80) De-macro the sysfs callbacks
    
    Use standard dynamic sysfs callbacks instead of macro-generated
    functions. This makes the code more readable, and the binary smaller
    (by about 34%).
    
    As a side note, another benefit of this type of cleanup is that they
    shrink the build time. For example, this cleanup saves about 29% of
    the lm80 driver build time.
