...
On the example, the ldac gpio is flagged as active high, when in reality
its an active low gpio. Fix the example by using the active low flag for
the ldac gpio.

dt-bindings: iio: dac: ad5791: Add optional reset, clr and ldac gpios
...
Depending on board layout, the ad57xx may need control of reset, clear,
and ldac pins by the host driver. Add optional bindings for these gpios.

dt-bindings: iio: dac: 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.

...
Documenting existing bindings for this device.
The Linux driver in theory 'works' without the two supplies that I have
listed as required, but without a valid scale. As such I've
documented it as required.
