hwmon: (lm90) Support ADT7461 in extended mode
Support ADT7461 in extended temperature range mode, which will change the range of readings from 0..127 to -64..191 degC. Adjust the register conversion functions accordingly.

The LM90 is a digital temperature sensor. It senses its own temperature as
well as the temperature of up to one external diode. It is compatible
-with many other devices such as the LM86, the LM89, the LM99, the ADM1032,
-the MAX6657, MAX6658, MAX6659, MAX6680 and the MAX6681 all of which are

Note that there is no easy way to differentiate between the MAX6657,
MAX6658 and MAX6659 variants. The extra address and features of the
MAX6659 are not supported by this driver. The MAX6680 and MAX6681 only
differ in their pinout, therefore they obviously can't (and don't need to)
-be distinguished. Additionally, the ADT7461 is supported if found in

The specificity of this family of chipsets over the ADM1021/LM84
family is that it features critical limits with hysteresis, and an
