Subject: drm/amd/display: Don't fill up the logs
Git-commit: 52e8da704d8d3ca8b951fbc39cf8d6bce5c33db8
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

Don't fill up the logs with:

[253557.859575] [drm:amdgpu_dm_atomic_check [amdgpu]] DSC precompute is not needed.
[253557.892966] [drm:amdgpu_dm_atomic_check [amdgpu]] DSC precompute is not needed.
[253557.926070] [drm:amdgpu_dm_atomic_check [amdgpu]] DSC precompute is not needed.
[253557.959344] [drm:amdgpu_dm_atomic_check [amdgpu]] DSC precompute is not needed.

which prints many times a second, when the kernel is run with
drm.debug=2.

Instead of DRM_DEBUG_DRIVER(), make it DRM_INFO_ONCE().
