Note: The bug (fail to init tonga) doesn't occur on my Carrizo system
so it definitely has something to do with the call to
dcn_bw_update_from_pplib() on my Raven.

With a Tonga dGPU installed in a Raven1 system I see (attached) dmesg
warning from init.
Also, every warm reboot results in my Tonga failing to init (also
attached). If I cold reboot (hit the reset button) it works fine.
Note I get the DCN message regardless if I warm or cold reboot.

drm/amd/display: Enable PPLib calls from DC on linux
Set the powerplay debug flag to false for both Windows and Linux
to allow the calls to pplib. So we can retrieve the clock values
from powerplay instead of using default hardcoded values.
