Krzysztof Kozlowski e4bb7fee18 dt-bindings: input: ariel-pwrbutton: use spi-peripheral-props.yaml
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.a

The binding references also input.yaml and lists explicitly allowed
properties, thus here reference only spi-peripheral-props.yaml for
purpose of documenting the SPI slave device and bringing
spi-max-frequency type validation.

description: |
The ENE Embedded Controller on the Ariel board has an interface to the
SPI bus that is capable of sending keyboard and mouse data. A single
power button is attached to it. This binding describes this
configuration.
