Subject: drm/amdgpu/runpm: enable runpm on baco capable VI+ asics
Git-commit: 4fdda2e66de0b7d37aa27af3c1bbe25ecb2d5408
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Seems to work reliably on VI+ except for a few so enable runpm barring
those where baco for runtime power management is not supported.
[rajneesh] Picked https://patchwork.freedesktop.org/patch/335402/ to
enable runtime pm with baco for kfd. Also fixed a checkpatch warning and
added extra checks for VEGA20 and ARCTURUS.
