[PATCH V4 2/6] dt-bindings: w1: Add DS2482/DS2484 I2C to 1-W bridges

[Stefan Wahren]

Even this binding look trivial, the actual hardware supports more
features (e.g. sleep mode control GPIO). So add this as a dedicated
devicetree binding for the Maxim DS2482/DS2484 I2C to 1-W bridges,
which can be extended later.
