Nord has a new MDSS 12.1 revision with DPU 1499A and two independent,
DP-only display interface controllers (no DSI), which no existing
schema describes. Add a dedicated qcom,nord-mdss binding to document.

+description:
+  Nord display subsystem consists of MDSS (display controller), DPU 1499A
+  (display processing unit), and display interface controllers (DP only, no 
DSI).
+  This is MDSS 12.1, DP-only, with 2 independent DP controllers.
