drm/amd/display: Fix refresh rate range for some panel

Browse source

[Why]
Some of the panels does not have the refresh rate range info
in base EDID and only have the refresh rate range info in
DisplayID block.
It will cause the max/min freesync refresh rate set to 0.

[How]
Try to parse the refresh rate range info from DisplayID if the
max/min refresh rate is 0.
