ASoC: dt-bindings: 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.
