[PATCH 3/3] arm64: dts: rockchip: add overlay for tiger-haikou video-demo adapter

From: Heiko Stuebner <heiko.stuebner at cherry.de>

This adds support for the video-demo-adapter for the Haikou devkit with
Tiger RK3588 SoM.

The Video Demo adapter is an adapter connected to the fake PCIe slot
labeled "Video Connector" on the Haikou devkit.

It's main feature is a Leadtek DSI-display with touchscreen. To drive these
components a number of additional regulators are grouped on the adapter as
well as a PCA9670 gpio-expander to provide the needed additional gpio-lines.
