[PATCH net-next 09/13] dt-bindings: net: airoha: Add airoha,npu phandle property

[Lorenzo Bianconi]

Introduce the airoha,npu property for the npu syscon node available on
EN7581 SoC. The airoha Network Processor Unit (NPU) is used to offload
network traffic forwarded between Packet Switch Engine (PSE) ports.
