Subject: drm/amd/powerplay: new cgs interface setting dpm thermal range
Git-commit: 1357f0c5ac357f0dfed8f900be7700d4d6bc152a
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

This will be used by powerplay to update the dpm temp range structure
used to interface with hwmon.
