dmesg for 4.17.11-200

When booting kernel 4.17 or 4.18-rc8+ (git) on a POWER9 system with an ASUS=
 Rx
580 GPU, the following messages are printed to the kernel log:

[   10.398837] amdgpu: [powerplay] There must be 1 or more PCIE levels defi=
ned
in PPTable.
[   10.398839] amdgpu: [powerplay] Failed to populate SCLK during
PopulateNewDPMClocksStates Function!
[   10.398840] amdgpu: [powerplay] Failed to populate and upload SCLK MCLK =
DPM
levels!


Note that the system is booted with the kernel argument `amdgpu.dc=3D0` to =
work
around this issue: https://bugs.freedesktop.org/show_bug.=
cgi?id=3D107049

GPU performance seems to be significantly hindered as a result of these err=
ors.

Booting with `amdgpu.dpm=3D0` silences the errors but does not improve
performance.
