OMAPDSS: TFP410: fix input sync signals
TFP410 requires that DE is active high and the data and syncs are driven on rising pixel clock edge. However, at the moment the driver doesn't request such syncs, and the end result is that the sync settings depend on default values, which are not right in all cases. Set the sync values explicitly.
