[Public] In the SMU issue troubleshooting process we also can check the SMU version by reading MP1 scratch register and from long term we may need put the SMC version collection in the debug sysfs amdgpu_firmware_info In this patch fashion, we better use dev_dbg instead of dev_info for only debug purpose.
Actually SMUv13 files have it at info level, which is why it was modeled this way. Perhaps v13 should also decrease this to debug then.
