From: Ray Wu <[email protected]> [Why] IGT link-training-configs test fails to set the link rate on Replay panels because some link rate types are not supported in debugfs. As a result, debugfs treats these link rates as invalid, causing the IGT test to fail.
[How] Add missing link rate types to resolve this issue.
