iGPU_MIGraphX: Host shuts down when running MIGraphX benchmark on Strix

[ThomasGmeinder]

Description

Running the MIGraphX benchmark commands from README section 3.2.6 causes the host amd-HCAR300-MI3 to switch itself off completely.

Steps to reproduce

On branch onnx-benchmark-iGPU_MIGraphX-support at commit f190bde:

python performance_benchmark.py --model resnet50 --execution_provider iGPU_MIGraphX --num 100 --timelimit 10

python performance_benchmark.py --model_path ./models/resnet50/resnet50_fp32.onnx --execution_provider iGPU_MIGraphX --migraphx_dtype fp16 --num 100 --timelimit 10

Both commands cause the host to shut itself off.

Expected behavior

The benchmark should complete and print a performance report without affecting system stability.
