As you can see, Fan, Temp and GPU-Util are not being reported. When running with `sudo`, Temp and GPU-Util gets reported. The temperatures and fan speeds are reported on `/sys/class/drm/renderD128/device/hwmon/hwmon2`, being readable by normal users. It would be nice if it didnt require `sudo xpu-smi` to read those values.

xpu-smi installed from https://github.com/intel/xpumanager/releases/tag/v2.0.1

Reproduce the report with xpu-smi as a normal user and with sudo, then inspect the handling of the reported fan, temperature, and GPU-util values. Compare access to /sys/class/drm/renderD128/device/hwmon/hwmon2 and verify that these values are reported without sudo while existing output remains correct.
