drm/amd/display: Populate Power Profile In Case of Early Return

Browse Source 
Early return possible if context has no clk_mgr.
This will lead to an invalid power profile being returned
which looks identical to a profile with the lowest power level.
Add back logic that populated the power profile and overwrite
the value if needed.
