36689e5750 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.

eb8d4d0d99 drm/radeon: enable smc fan control on CI
This seems to work well on CI boards after fixing the
last few bugs noticed by Chernovsky Oleg.

On boards with a high default fan speed this should
reduce fan noise.  Manual fan control is not enabled
yet.

6c7bccea39 drm/radeon/pm: move pm handling into the asic specific code
We need more control over the ordering of dpm init with
respect to the rest of the asic.  Specifically, the SMC
has to be initialized before the rlc and cg/pg.  The pm
code currently initializes late in the driver, but we need
it to happen much earlier so move pm handling into the asic
specific callbacks.

This makes dpm more reliable and makes clockgating work
properly on CIK parts and should help on SI parts as well.
