drm/amd/display: Add SMU logging code

commit 4b33b5ffcf68de3a43e7dddc91c5dc86e6ed8587 upstream.

[WHY]
Logging for SMU response value after the wait allows us to know
immediately what the response value was. Makes it easier to debug should
the value be anything other than OK.

[HOW]
Using the the already available DC SMU logging functions.
