dt-bindings: display: msm: Fix reg ranges and clocks on Glymur

The Glymur platform has four DisplayPort controllers. The hardware
supports four streams (MST) per controller. However, on Glymur the first
three controllers only have two streams wired to the display subsystem,
while the fourth controller operates in single-stream mode.

Add a dedicated clause for the Glymur compatible to require the register
ranges for all four stream blocks, while allowing either one pixel clock
(for the single-stream controller) or two pixel clocks (for the remaining
controllers).

Update the Glymur MDSS schema example by adding the missing p2, p3,
mst2link and mst3link register blocks. Without these, the bindings
validation fails. Also replace the made-up register addresses with the
actual addresses from the first controller to match the SoC devicetree
description.
