[PATCH 2/2] dt-bindings: hwmon: add EMC181x

[Mark Tomlinson]

The EMC181x range are I2C temperature sensors with a varying number of
sensors in each device. Each has one internal sensor, and one to four
external sensor diodes.

The default range is from 0°C to +127°C, but can be extended to -64°C to
+191°C.
