arm64: dts: rockchip: add overlay for tiger-haikou video-demo adapter 

This adds support for the video-demo-adapter DEVKIT ADDON CAM-TS-A01
(https://embedded.cherry.de/product/development-kit/

) 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 and a camera
(that is not supported yet). 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.
