Bug description:
Quoted from AMD proposed fix in https://lore.kernel.org/amd-
gfx/[email protected]/T/#m94e3b7d292e359f3d656babe3ccdbf7fc6daab6f
> The monitor shipped with the Framework 16 supports VRR [1], but it's not
> being advertised.
>
> This is because the detailed timing block doesn't contain
> `EDID_DETAIL_MONITOR_RANGE` which amdgpu looks for to find min and max
> frequencies. This check however is superfluous for this case because
> update_display_info() calls drm_get_monitor_range() to get these ranges
> already.
>
> So if the `DRM_EDID_FEATURE_CONTINUOUS_FREQ` EDID feature is found then
> turn on freesync without extra checks.
