dt-bindings: iio: adc: add maxim,max40080

This commit adds device tree bindings for the Maxim MAX40080 bidirectional
current-sense amplifier. It defines standard properties and parameters like
the shunt resistor value used for scaling the reported current.

[Severity: Low]
The commit message mentions an internal FIFO, which usually implies an
interrupt pin is available to signal data ready or alerts. Physical devices
also typically have power supply requirements, such as a vdd-supply.

Since additionalProperties is set to false, will device trees that accurately
describe these physical hardware connections fail schema validation? Should
definitions for interrupts or power supplies be added to the properties block
to bypass the additionalProperties restriction?
