Subject: [PATCH] spi: dt-bindings: arm,pl022: Move child node properties to separate schema
In order to validate SPI peripherals, SPI controller-specific child node
properties need to be in a separate schema, spi-peripheral-props.yaml,
which SPI peripheral schemas reference. Move the arm,pl022 child
properties to their own schema file and add a $ref in
spi-peripheral-props.yaml.
