I have learnt something new today, CONFIG_EXTRA_FIRMWARE is not needed for
modules.

I tried RADEON_DPM_FORCED_LEVEL_LOW and RADEON_DPM_FORCED_LEVEL_HIGH, but they
didn't work either.

Then I commented out:
ni_dpm_force_performance_level(rdev, RADEON_DPM_FORCED_LEVEL_AUTO);

With that I can boot the system and dpm seems to work, because the fan is nice
and quiet. Also cat /sys/kernel/debug/dri/64/radeon_pm_info says this:
uvd    vclk: 0 dclk: 0
power level 0    sclk: 25000 mclk: 15000 vddc: 900 vddci: 950

Then (with RADEON_DPM_FORCED_LEVEL_AUTO enabled again) I commented out:
if (ni_send_msg_to_smc_with_parameter(rdev, PPSMC_MSG_SetForcedLevels, 0) !=
PPSMC_Result_OK)

That resulted in screen corruption but it worked when I instead commented out:
if (ni_send_msg_to_smc_with_parameter(rdev, PPSMC_MSG_SetEnabledLevels, 0) !=
PPSMC_Result_OK)
