Subject: drm/amdgpu/powerplay: add renoir funcs to support dc
Git-commit: 7bbdbe405965dc4998996bdea571a5b9a1dd3d16
Patch-mainline: v5.5-rc1
References: bsc#1152489
there are two paths for renoir dc access smu.
one dc access smu directly using bios smc
interface: set disply, dprefclk, etc.
another goes through pplib for get dpm clock
table and set watermmark.
