This patch is used for virtualization support. In virtualization, only SMU manager is needed, DPM should be disabled. This is a use case for commit 2f9346b6f984 ("drm/amdgpu/powerplay: pp module only enable smu when dpm disabled.") Change in V2, according to Christian's suggestion, This patch will not mess with module parameters amdgpu_dpm, but make that a dependency for when amdgpu_dpm is evaluated.
