This currently fixes the remaining dtb warnings:
Node /pcie@1e140000/pcie0 has a reg or ranges property, but no unit name
Node /pcie@1e140000/pcie1 has a reg or ranges property, but no unit name
Node /pcie@1e140000/pcie2 has a reg or ranges property, but no unit name
Node /pcie@1e140000/pcie0 node name is not "pci" or "pcie"
Node /pcie@1e140000/pcie0 missing ranges for PCI bridge (or not a bridge)
Node /pcie@1e140000/pcie0 missing bus-range for PCI bridge
Node /pcie@1e140000/pcie1 node name is not "pci" or "pcie"
Node /pcie@1e140000/pcie1 missing ranges for PCI bridge (or not a bridge)
Node /pcie@1e140000/pcie1 missing bus-range for PCI bridge
Node /pcie@1e140000/pcie2 node name is not "pci" or "pcie"
Node /pcie@1e140000/pcie2 missing ranges for PCI bridge (or not a bridge)
Node /pcie@1e140000/pcie2 missing bus-range for PCI bridge
Warning (unit_address_format): Failed prerequisite 'pci_bridge'
Warning (pci_device_reg): Failed prerequisite 'pci_bridge'
Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge'
In addition, it sets each pcie port to disabled in order to allow future
boards to be added that only have 1 or 2 pcie lanes wired up. gbpc1.dts
was changed to accomidate.
