[PATCH v4 3/4] dt-bindings: hwmon: (pmbus/max20830): add max20830c and max20840c support

[Alexis Czezar Torreno <alexisczezar.torreno@analog.com>]

Add compatible strings for variants of MAX20830 which are MAX20830C
and MAX20840C. These devices have the same register functionality with
MAX20830 but with a longer IC_DEVICE_ID.
