[PATCH next 3/3] rockchip: ringneck-px30: enable DT overlay support

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at cherry.de>

Haikou carrierboard allows multiple adapter boards to be connected, for
now there exists the following adapter boards compatible with PX30
Ringneck:
 - Haikou Video Demo on the Video Connector,
 - Haikou LVDS 9904379 on the Video Connector,

So support DT overlays so we can use this mechanism instead of full DTB
containing both the carrierboard and the adapter.
