Could be we've got a race condition between the powerplay setup and amdgpu
handing off the card to drm_dev_register to advertise it for normal use.
drm_dev_register is responsible for the "[drm] Initialized" message:
https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/drm_drv.c#L994
And it seems like amdgpu calls it here:
https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c#L1054
Odd that it's doing this if powerplay still has more work to do. And that might
be why vega20_set_uclk_to_highest_dpm_level fails that last time.
