drm/amd/display: Only enumerate top local sink as DP2 output
[WHY]
Many DCN generations only have two HPO link encoders and therefore only
support driving a max of two DP2 PHYs. DP2 MST hubs currently can not
pass 3x display validation as each downstream sink is enumerated as
separate DP2 output.
[HOW]
Count MST hubs once by treating only 1st remote sink in topology as an
encoder.
