Subject: [PATCH] spi: dt-bindings: st,stm32-spi: Move "st,spi-midi-ns" to spi-peripheral-props.yaml

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. As there is just a single
property in this case, just add it to spi-peripheral-props.yaml directly.
