ipq40xx: dts: fix incorrect PCIe bus number

On the ipq40xx platform, the bus range is 1 - 255. Therefore, bus
number 0 is clearly incorrect. Change the bus number to 1, just
like other ipq40xx devices. This patch fixes the following dtc
warnings on 6.12 kernel:

qcom-ipq4019.dtsi:476.5-29: Warning (pci_device_bus_num): /soc/pcie@40000000/pcie@0/wifi@0,0:bus-range: PCI bus number 0 out of range, expected (1 - 255)
qcom-ipq4019.dtsi:476.5-29: Warning (pci_device_bus_num): /soc/pcie@40000000/pcie@0/wifi@0,0:bus-range: PCI bus number 0 out of range, expected (1 - 255)
