Revert "drm/amd/display: Expose connector VRR range via debugfs"

v3:
* Rebase (Manasi)
v2:
* Rebase (Manasi)

As both VRR min and max are already part of drm_display_info,
drm can expose this VRR range for each connector.

Hence this logic should move to core DRM.

This reverts commit 727962f030c23422a01e8b22d0f463815fb15ec4.
