[PATCH] drm/amdgpu/powerplay: add renoir funcs to support dc

Regards the comment inline, saw you have fixed the not enable CONFIG_DRM_AMD_DC_DCN2_1 potential compile issue.
BTW, would you help clarify why PP_SMU_NUM_DCFCLK_DPM_LEVELS is different from the smu12_driver_if.h define NUM_DCFCLK_DPM_LEVELS .
Is there can track the macro definition update ?
Thanks,
Prike
