display/amd: decrease message verbosity about watermarks table failure
[ Upstream commit 03ad3093c7c069d6ab4403730009ebafeea9ee37 ]
A number of BIOS versions have a problem with the watermarks table not
being configured properly. This manifests as a very scary looking warning
during resume from s0i3. This should be harmless in most cases and is well
understood, so decrease the assertion to a clearer warning about the problem.
