[PATCH v2 3/3] arm64: dts: rockchip: support camera module on Haikou Video Demo on PX30 Ringneck

[Quentin Schulz]

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

The Haikou Video Demo adapter has a proprietary connector for a camera
module which has an OV5675 camera sensor and a companion DW9714 focus
lens driver.

This adds support for the camera module on PX30 Ringneck module fitted
on a Haikou devkit with the Haikou Video Demo adapter.
