Subject: drm/amd/display: avoid printing ERROR for unknown CEA parse(v2)
Git-commit: b76a8062af2f3be08038e927aafb116e84053374
Patch-mainline: v5.15-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

For the unknown CEA parse case on DMUB-enabled ASICs, dmesg will
print an error message like below, this will be captured by
automation tools as it has the word like ERROR during boot up
and treated as a false error, as it does not break bootup process.
So use DRM_WARN printing for this.

[drm:amdgpu_dm_update_freesync_caps [amdgpu]] *ERROR* Unknown EDID CEA parser results

v2: Use DRM_WARN to print such info.
