Subject: [PATCH] drm/amd/display: Populate Power Profile In Case of Early
Return

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.
