Subject: drm/amd/powerplay: add new UMD pstate data structure
Git-commit: b64d86889f1e66190fa54a9626a1333dd653bad6
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
This is used to cache the clock frequencies for all UMD pstates.
So that we do not need to calculate from scratch on every UMD
pstate switch.
