Add support for Arm Ethos-N NPU multi-device. The device tree parsing currently only supports one NPU device with multiple cores. To be able to support multi-device NPU configurations this patch adds support for having multiple NPU devices in the device tree. To be able to support multiple NPU devices in the SMC API, it has been changed in an incompatible way so the API version has been bumped.
