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

Browse Source 
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 */
};
