drm/amdgpu/runpm: enable runpm on baco capable VI+ asics

Browse source 
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.
