[PATCH 3/3] arm64: dts: rockchip: Add Anbernic RG351V

[Chris Morgan]

From: Chris Morgan <macromorgan at hotmail.com>

Add support for the Anbernic RG351V, which is a handheld gaming console
from Anbernic with an RK3326 SoC, a 640x480 LCD display, a single
analog joystick with several face buttons, two USB C ports, and
internal WiFi over USB. All hardware has been tested as working
except for the battery, which will require further modification to the
mainline rk817 battery driver before it can be used (the device was
built without a shunt resistor, and as such the battery cannot
measure current; only voltage).
