[PATCH v6 1/4] arm64: dts: rockchip: add overlay test for WolfVision PF5

[Quentin Schulz]

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

The WolfVision PF5 can have a PF5 Visualizer display and PF5 IO Expander
board connected to it. Therefore, let's generate an overlay test so the
application of the two overlays are validated against the base DTB.
