drm/amd/display: Add SMU logging code

commit 4b33b5ff

 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.
