[PATCH] arm64: dts: rockchip: add wolfvision pf5 visualizer display

[Michael Riesch <michael.riesch@wolfvision.net>]

Add device tree overlay for the WolfVision PF5 Visualizer display.
Since there shall be additional variants of the WolfVision PF5 display in
future, move common definitions to a device tree include file.

Signed-off-by: Michael Riesch <michael.riesch@wolfvision.net>

Habidere,

A further addition related to the WolfVision PF5 mainboard that
has been accepted recently.

Looking forward to your comments!
