drm/amd/display: Use freesync when `DRM_EDID_FEATURE_CONTINUOUS_FREQ` found
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.
v2: squash in fix from Harry
