The Glymur platform has four DisplayPort controllers. All the controllers support four streams (MST). However, the first three only have two streams wired up physically to the display subsystem, while the fourth controller has only one stream (SST).
So add a dedicated clause for Glymur compatible to enforce reg ranges to describing all four streams while allowing either one pixel clock, for the third DP controller, or two pixel clocks, for the rest of them.
