[PATCH 12/14] ARM: dts: rockchip: rv1126: Add Edgeble Neu2 IO DSI overlay

[Jagan Teki <jagan@edgeble.ai>]

Add DSI pipeline for Edgeble Neu2 IO board via DT-overlay

The DSI connector in Edgeble Neu2 IO board support different
resolution panels and those compatible is added in another
DT-overlay.

Add Edgeble Neu2 IO DSI connector DT-overlay.
