Alex Deucher 5e8150a687 drm/radeon: bind fan control on SI cards to hwmon interface
This adds a possibility to control fan on SI parts
via exported hwmon variables. Note that automatic
ucode fan management pauses if you choose to enable
manual fan control.  Use with caution!

Alex Deucher a9e6141092 drm/radeon/kms: add dpm support for SI (v7)
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
v7: attempt fix state enable
