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!

39471ad39d drm/radeon/dpm: add smc fan control for SI (v2) 
Enable smc fan control for SI boards.  Should
reduce the fan noise on systems with a higher
default fan profile.

v2: disable by default, add rpm controls

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
