Subject: drm/amd/pp: Implement update_dpm_settings on Polaris
Git-commit: 2107f580909f96abe82df0ca164006b3454e983b
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
v2: lock dpm level when update pptable by SW method
use SW method to update DPM settings by updating SRAM
directly on Polaris.
