ARM: dts: mmp2-olpc-xo-1-75: clear the warnings when make dtbs
The check_spi_bus_bridge() in scripts/dtc/checks.c requires that the node have "spi-slave" property must with "#address-cells = <0>" and "#size-cells = <0>". But currently both "#address-cells" and "#size-cells" properties are deleted, the corresponding default values are 2 and 1. As a result, the check fails and below warnings is displayed. arch/arm/boot/dts/mmp2.dtsi:472.23-480.6: Warning (spi_bus_bridge): \ /soc/apb@d4000000/spi@d4037000: incorrect #address-cells for SPI bus also defined at arch/arm/boot/dts/mmp2-olpc-xo-1-75.dts:225.7-237.3 arch/arm/boot/dts/mmp2.dtsi:472.23-480.6: Warning (spi_bus_bridge): \ /soc/apb@d4000000/spi@d4037000: incorrect #size-cells for SPI bus also defined at arch/arm/boot/dts/mmp2-olpc-xo-1-75.dts:225.7-237.3 arch/arm/boot/dts/mmp2-olpc-xo-1-75.dtb: Warning (spi_bus_reg): \ Failed prerequisite 'spi_bus_bridge' Because the value of "#size-cells" is already defined as zero in the node "ssp3: spi@d4037000" in arch/arm/boot/dts/mmp2.dtsi. So we only need to explicitly add "#address-cells = <0>" and keep "#size-cells" no change.
