Instead of listing directly properties typical for SPI peripherals, reference the spi-peripheral-props.yaml schema. This allows using all properties typical for SPI-connected devices, even these which device bindings author did not tried yet. Remove the spi-* properties which now come via spi-peripheral-props.yaml schema, except for the cases when device schema adds some constraints like maximum frequency. While changing additionalProperties->unevaluatedProperties, put it in typical place, just before example DTS.

AD5421 is designed for us in loop-powered, 4 mA to 20 mA smart transmitter
|
|
applications. It provides a 16-bit DAC, current amplifier, voltage regulator
|
|
to drive the loop and a voltage reference.
