The change would add more IP block support in amdgpu_dpm_set_powergating_by_smu For GFX/UVD/VCN/VCE, if the new SMU driver is supported, invoke new power gate helper function smu_dpm_set_power_gate, otherwise, fallback to legacy powerplay helper function pp_set_powergating_by_smu. For other IP blocks always invoke legacy powerplay helper function.
