drm/amd/display: Fix phy id mapping issue for secure display
[Why]
Under mst scenario, mst streams are from the same link_enc_hw_inst.
As the result, can't utilize that as the phy index for distinguising
different stream sinks.
[How]
Sort the connectors by:
link_enc_hw_instance->mst tree depth->mst RAD
After sorting the phy index assignment, store connector's relevant info
into dm mapping array. Once need the index, just look up the static
array.
