drm/i915/mst: enable MST mode for 128b/132b single-stream sideband

If the sink supports 128b/132b and single-stream sideband messaging,
enable MST mode.

With this, the topology manager will still write DP_MSTM_CTRL, which
should be ignored by the sink. In the future, the topology manager
should probably only set the sideband messaging related parts of the
register.
