dt-bindings:iio:potentiometer:maxim,max5481 move to trivial devices 



Simple SPI binding that doesn't need a separate file.
During conversion I looked up the individual part number descriptions
in the datasheet so that we could give slightly more detail in
trivial-device.yaml.

* Maxim Linear-Taper Digital Potentiometer MAX5481-MAX5484



The node for this driver must be a child node of a SPI controller, hence

all mandatory properties described in



        Documentation/devicetree/bindings/spi/spi-bus.txt



must be specified.



Required properties:

	- compatible:  	Must be one of the following, depending on the

			model:

			"maxim,max5481"

			"maxim,max5482"

			"maxim,max5483"

			"maxim,max5484"



Example:

max548x: max548x@0 {

	compatible = "maxim,max5482";

	spi-max-frequency = <7000000>;

	reg = <0>; /* chip-select */

};
