dt-bindings: power: supply: max17042: add support for max77759

The Maxim MAX77759 is a companion PMIC intended for use in mobile
phones and tablets. It is used on Google Pixel 6 and 6 Pro (oriole and
raven). Amongst others, it contains a fuel gauge that is similar to the
ones supported by this binding.

The fuel gauge can measure battery charge and discharge current,
battery voltage, battery temperature, and the Type C connector's
temperature.
