drm/amd/display: fix graphics hang in multi-display mst case
[what]
Graphics hang observed with 3 displays connected to DP2.0 mst dock.
[why]
There's a mismatch in dml and dc between the assignments of hpo link
encoders.
[how]
Add a new array in dml that tracks the current mapping of HPO stream
encoders to HPO link encoders in dc.
