Enable smc fan control for CI boards.  Should
reduce the fan noise on systems with a higher
default fan profile.

v2: disable by default, add additional fan setup, rpm control

in itself, but reducing warning count from 391 to 258 may help

Otherwise, we end up setting the thermal ranges

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.

Right now it's called right after enable, but after
reworking the dpm init order, it will get called later
to accomodate loading the smc early, but enabling
thermal interrupts and block powergating later after
the ring tests are complete.
Signed-off-by: NAlex Deucher <alexander.deucher@amd.com>

Make sure interrupts are enabled
before we enable thermal interrupts.
Also, don't powergate uvd until after
the ring tests.

Filter out mclk and sclk levels higher than listed in the clk

Calling force_performance_level() from set_power_state()
doesn't work on some asics because the current power
state pointer has not been properly updated at that point.
Move the calls to force_performance_level() out of the
asic specific set_power_state() functions and into
the main power state sequence.

Fixes dpm resume on SI.

Check to make sure the dc limits are valid before using them.
Some systems may not have a dc limits table.  In that case just
use the ac limits.  This fixes hangs on systems when the power
state is changed when on battery (dc) due to invalid performance
state parameters.

Should fix:
