Add empty ranges properties to silence such warnings:
arch/arm/boot/dts/bcm5301x.dtsi:240.21-246.5: Warning (pci_bridge): /axi@18000000/pcie@12000: missing ranges for PCI bridge (or not a bridge)
arch/arm/boot/dts/bcm5301x.dtsi:248.21-254.5: Warning (pci_bridge): /axi@18000000/pcie@13000: missing ranges for PCI bridge (or not a bridge)
arch/arm/boot/dts/bcm5301x.dtsi:256.21-262.5: Warning (pci_bridge): /axi@18000000/pcie@14000: missing ranges for PCI bridge (or not a bridge)
to silence warnings. This is not a functional issue since the driver does not
make use of the OF infrastructure for registering the PCIe controller(s) on
this chip, but uses the BCMA bus.
