We don't need this as a generic ppt_func. Reset functionalities are changing over programs and this could be valid only for Arcturus. Please move it to Arcturus swsmu late init.
Thanks,
Lijo

Subject: [PATCH] drm/amdgpu: Enable light SBR in XGMI+passthrough configuration
This is to fix the commit dda9bbb26c7 where it only enable the light SMU on normal device init. This feature actually need to be enabled after ASIC been reset as well.
