Subject: drm/amd/pp: Adding a function to store cc6 data in SMU10
Git-commit: 5c3517d0c2ead443f378173c698f3bd09cb89d72
Patch-mainline: v4.18-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Filling the smu10_store_cc6_data based on the implementation
of Windows Powerplay.

There is an uncertainty with one of the parameters passed to the function
pstate_switch_disable - is not a part of smu10 private data structure.
So in the function its just ignored.
