Subject: drm/amd/powerplay: update the common API for performance level
Git-commit: 768bb9010aeb662071129d1b92d82c45d060a7d6
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
 setting

So that it can be more widely shared around SMU v11 ASICs.
