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.

Update bindings to describe support for buffered and unbuffered external
voltage references selection, and add adi,internal-ref-microvolt for
internal voltage reference selection.

Simple SPI driver. I've added the #io-channel-cells
as an optional parameter to allow use of this device as a provider
of ADC capabilities to other devices.
