This was added a helper for amdgpu to workaround a runtime pm regression caused by a runtime pm fix in efifb. We now have a better workarouund in amdgpu in commit f95af4a9236695 ("drm/amdgpu: don't runtime suspend if there are displays attached (v3)") so this workaround is no longer necessary. Since amdgpu was the only user of this interface, we can remove it.
