of: address: Work around missing device_type property in pcie nodes
Recent changes to the DT PCI bus parsing made it mandatory for device tree nodes describing a PCI controller to have the 'device_type = "pci"' property for the node to be matched. Although this follows the letter of the specification, it breaks existing device-trees that have been working fine for years. Rockchip rk3399-based systems are a prime example of such collateral damage, and have stopped discovering their PCI bus. In order to paper over it, let's add a workaround to the code matching the device type, and accept as PCI any node that is named "pcie", A warning will hopefully nudge the user into updating their DT to a fixed version if they can, but the incentive is obviously pretty small.
