fdt: Fix phandles for NVLink/NVLink2
The NVIDIA driver for NVLink2-capable GPU NVIDIA V100 discovers topology
between GPU/NPUs/GPURAM via the device tree which needs to have cross
references between device tree nodes.
This adds patching of the nodes needed for the driver to initialize.
As all these properties only contain phandles and nothing else, there is
no risc of accidendal damage.
