Subject: [PATCH v3 2/3] spi: dt-bindings: cdns,qspi-nor: Move peripheral-specific properties out

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