drm/amd/powerplay: update the data structure for NV12 SmuMetrics
Although it does not bring any problem for now, the coming gpu metrics interface needs to handle them differently based on the asic type. Signed-off-by: Evan Quan <evan.quan@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
