drm/amd/dm: Don't forget to attach MST encoders
The change fixed huge delay in SST daisy chain and S3 soft hang
observed in 4.19 kernel rebase.
Regression point in drm:
drm/fb-helper: Eliminate the .best_encoder() usage
The aux sequence is altered due to the failure in
drm_connector_for_each_possible_encoder(). The failure is
caused by missing attached encoder in the process of adding
MST connector.
drm_dp_send_enum_path_resources() aux transaction is pushed after
mode probe, which causes conflict to drm_dp_mst_i2c_xfer(),
leading to the transaction timeout.
