Browse Source 
This adds dpm support for SI asics.  This includes:
- dynamic engine clock scaling
- dynamic memory clock scaling
- dynamic voltage scaling
- dynamic pcie gen1/gen2/gen3 switching
- power containment
- shader power scaling

Set radeon.dpm=1 to enable.

v2: enable hainan support, rebase
v3: guard acpi stuff
v4: fix 64 bit math
v5: fix 64 bit div harder
v6: fix thermal interrupt check noticed by Jerome
