[PATCH 4/6] dt-bindings: misc: explicitly list SPI CPHA and CPOL

[Krzysztof Kozlowski]

The spi-cpha and spi-cpol properties are device specific and should be
accepted only if device really needs them.  Explicitly list them in
device bindings in preparation of their removal from generic
spi-peripheral-props.yaml schema.
