[PATCH] drm/amdgpu: Enable SMU 13.0.0 optimizations when ROCm is active

[Wang, Yang(Kevin)]

Hi Alex,

why need to switch profile twice for smu 13.0.0 ? in idle state : set compute profile then set power save profile?
Afaik, Pmfw always uses the last set result to represent the current profile.
But it shouldn't affect the results. Anyway.
