"4c3b89e powerpc/powernv: Add sanity checks to pnv_pci_get_{gpu|npu}_dev"
introduced explicit warnings in pnv_pci_get_npu_dev() when a PCIe device
has no associated device-tree node. However not all PCIe devices have an
of_node and pnv_pci_get_npu_dev() gets indirectly called at least once for
every PCIe device in the system. This results in spurious WARN_ON()'s so
remove it.
The same situation should not exist for pnv_pci_get_gpu_dev() as any NPU
based PCIe device requires a device-tree node.
