Subject: [PATCH 4/6] dt-bindings: misc: explicitly add #address-cells for slave mode

Explicitly add "#address-cells = <0>" and "#size-cells = <0>" to
eliminate below warnings.

(spi_bus_bridge): /example-0/spi: incorrect #address-cells for SPI bus
(spi_bus_bridge): /example-0/spi: incorrect #size-cells for SPI bus
(spi_bus_reg): Failed prerequisite 'spi_bus_bridge'
