drm/amd: Remove freesync video mode amdgpu parameter

[Why&How]
Freesync Video mode was enabled by default. Hence no need for the module
parameter, so remove it completely

- * used refresh rates and VRR range of the connected display, when users enable
- * this feature. From the userspace perspective, they can see a seamless mode

- * can read this modeset list and change the refresh rate based on the video
- * frame rate. Finally, the userspace can also derive an appropriate mode for a
- * particular refresh rate based on the FreeSync Mode and add it to the
- * connector's mode list.
- *
- * Note: This is an experimental feature.
