drm/amdgpu: Add preferred mode in modeset when freesync video mode's enabled.
[Why] With kernel module parameter "freesync_video" is enabled, if the mode is changed to preferred mode(the mode with highest rate), then Freesync fails because the preferred mode is treated as one of freesync video mode, and then be configurated as freesync video mode(fixed refresh rate). [How] Skip freesync fixed rate configurating when modeset to preferred mode. Signed-off-by:Solomon Chiu <solomon.chiu@amd.com> Signed-off-by:
