arm64: dts: rockchip: add support for HAIKOU-LVDS-9904379 adapter for PX30 Ringneck 



The HAIKOU-LVDS-9904379 adapter is an adapter for PX30 Ringneck with the
Haikou carrierboard. It is to be inserted in the fake PCIe slot labelled
Video Connector.

This adapter expects an Admatec 9904379 1024x600 LVDS display with
backlight and touchscreen. An EEPROM is also found on the adapter.

This adds support for this adapter on PX30 Ringneck when inserted in
Haikou carrierboard.
