hwmon: (lm95241) Use more accurate limits
The lower temperature limit is -128 degrees C. The supported upper limits
are 127.875 or 255.875 degrees C. Also, don't fail if a value outside
the supported range is provided when setting a temperature limit.
Instead, clamp the provided value to the available value range.
