drm/amd/display: Add is_mst_connector debugfs entry
[Why & How]
Add "is_mst_connector" debugfs entry to help distinguish whether
a connector is in a mst topology or not.
Access it with the following command:
cat /sys/kernel/debug/dri/0/DP-X/is_mst_connector
Result:
- "root" stands for the root connector of the topology
- "branch" stands for branch device of the topology
- "end" stands for leaf node connector of the topology
- "no" stands for the connector is not a device of a mst topology
