tools/litex_json2dts: Fix SPI bus #size-cells 

As per Documentation/devicetree/bindings/spi/spi-controller.yaml,
"#size-cells" must be zero for a PCI bus.

This gets rid of the following build warnings:

    build/orangecrab/orangecrab.dts:105.29-39: Warning (reg_format): /soc/spi@f0004800/mmc-slot@0:reg: property has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1)
    buildroot/rv32.dtb: Warning (pci_device_reg): Failed prerequisite 'reg_format'
    buildroot/rv32.dtb: Warning (pci_device_bus_num): Failed prerequisite 'reg_format'
    buildroot/rv32.dtb: Warning (simple_bus_reg): Failed prerequisite 'reg_format'
    buildroot/rv32.dtb: Warning (i2c_bus_reg): Failed prerequisite 'reg_format'
    build/orangecrab/orangecrab.dts:91.46-110.19: Warning (spi_bus_bridge): /soc/spi@f0004800: incorrect #size-cells for SPI bus
    buildroot/rv32.dtb: Warning (spi_bus_reg): Failed prerequisite 'reg_format'
    buildroot/rv32.dtb: Warning (spi_bus_reg): Failed prerequisite 'spi_bus_bridge'
