The patch "drm/displayid: add quirk to ignore DisplayID
checksum errors" introduced a mechanism to bypass checksum validation
for certain panels. However, even when ignoring the error, the code
continues to log a DRM_NOTE.

On affected hardware, this results in persistent "DisplayID checksum
invalid" messages in the system log. This noise often misleads users
into thinking there is a critical hardware failure or a functional
regression, despite the quirk successfully handling the issue.

Downgrade the log level from DRM_NOTE to DRM_DEBUG_KMS. This keeps
the diagnostic information available for kernel developers while
silencing the unnecessary warning for end-users.
