Bug description:
  Turns out that Displayport Multi-Stream Transport has not been
  implemented for Skylake, causing blank screen issues (now that hangs
  have been fixed..) when plugging external displays to outputs
  connected to the MST hub. Disabling DP MST allows at least one of the
  outputs to work, if there are several behind the hub.
