[PATCH v2 2/3] spi: dt-bindings: cdns, qspi-nor: Move slave-specific properties out

[Pratyush Yadav]

The spi-slave-props.yaml schema contains slave-specific properties
for SPI controllers that should be present in the slave node. Move
slave-specific properties to a separate file and refer to it in
spi-slave-props.yaml.
