Jon Hunter 3ad362efba arm64: tegra: Resize aperture for the IGX PCIe C5 slot ...

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.
