drm/radeon/kms: add dpm support for rv6xx (v3)
This adds dpm support for rv6xx asics. This includes:
- clockgating
- dynamic engine clock scaling
- dynamic memory clock scaling
- dynamic voltage scaling
- dynamic pcie gen1/gen2 switching
Set radeon.dpm=1 to enable.
v2: remove duplicate line
v3: fix thermal interrupt check noticed by Jerome
