amd/display: downgrade validation failure log level
[ Upstream commit 7bbee36d71502ab9a341505da89a017c7ae2e6b2 ]
In amdgpu_dm_atomic_check, dc_validate_global_state is called. On
failure this logs a warning to the kernel journal. However warnings
shouldn't be used for atomic test-only commit failures: user-space
might be perfoming a lot of atomic test-only commits to find the
best hardware configuration.
Downgrade the log to a regular DRM atomic message. While at it, use
the new device-aware logging infrastructure.
This fixes error messages in the kernel when running gamescope [1].
