[PATCH v3 1/3] dt-bindings: hwmon: lm75: add MAX31875

[John Erasmus Mari Geronimo]

Add MAX31875 compatible string to lm75 dt-bindings.

The MAX31875 cannot reuse an existing lm75-family compatible such as
adi,adt75: it has a 16-bit configuration register (instead of 8-bit),
four independently selectable conversion rates (125 ms, 250 ms, 1 s,
4 s) and four independently selectable resolutions (8, 9, 10, 12
bits), and reports its alarm through a different configuration
register bit. These differences require dedicated handling in the
lm75 driver, so a distinct compatible string is needed to select it.
