Recent changes to the way PCI DT nodes are parsed are now enforcing the presence of a "device_type" property, which has been mandated since... forever. This has the unfortunate effect of breaking non-compliant systems, and those using the Rockchip PCIe driver are amongst the victims. Oh well. In order to keep users happy as well as my own machines up and running, let's paper over the problem by detecting a broken DT from the driver itself, and inserting the missing property at runtime. For a good measure, a second patch fixes the DT, but the chances of such a fix being deployed at this stage are pretty slim, so the above hack is in for the long run.
