spi-controller.yaml already defines this.

spi-controller.yaml says '#address-cells' must be 0 or 1. As RPC-IF does
SPI master only, it should be 1.

Don't remember why I added the '#size-cells' too. Perhaps for symmetry?

Yes, but then it says:

allOf:
- if:
not:
required:
- spi-slave
then:
properties:
"#address-cells":
const: 1
else:
properties:
"#address-cells":
const: 0
