drm/amd/display: Fix IGT link training failure on Replay panel 



[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.
