drm/radeon: bind fan control on CI cards to hwmon interface (v2)
This adds a possibility to control fan on CI parts
via exported hwmon variables. Note that automatic
ucode fan management pauses if you choose to enable
manual fan control. Use with caution!
v2: agd5f: fix formatting, squash in:
minor fix for pwm1_enable exposed value
Track smc control in addition to fan mode
This fixes pwm1_enable being constantly set
to 1 because of enabled smc control
also handle the case where smc fan control is disabled.
