Currently, besides there is no explicit message, that DPM is disabled.
The user would need to know, that the missing success line indicates
that.
[drm] amdgpu: dpm initialized
So, add an explicit message, and make it log level warning, as disabling
dpm is not the default, and device performance will most likely suffer.
