spi: dt-bindings: spi-controller: Fix #address-cells for slave mode
Currently, the DT bindings for an SPI controller specify that
"#address-cells" must be fixed to one. However, that applies to an SPI
controller in master mode only. When running in SPI slave mode,
"#address-cells" should not be specified.
Fix this making "#address-cells" mutually-exclusive with "spi-slave".
Fixes: 0a1b929356830257 ("spi: Add YAML schemas for the generic SPI options")
