spi: dt-bindings: allwinner: simplify with unevaluatedProperties
Remove properties already mentioned by common spi-controller.yaml and
switch to unevaluatedProperties:false to achieve same functional effect.
This makes the binding a bit smaller. Similarly there is no need to
allow additionalProperties for children, because spi-controller.yaml
already does it.
