Some discrete graphics cards such as the NVIDIA RTX A6000 support resizable BARs. When connecting an A6000 card to the NVIDIA IGX Orin platform, resizing the BAR1 aperture to 8GB fails because the current device-tree configuration for the PCIe C5 slot cannot support this. Fix this by updating the device-tree 'reg' and 'ranges' properties for the PCIe C5 slot to support this.
