arm64: dts: rockchip: Add Powkiddy RGB10MAX3

Add support for the Powkiddy RGB10MAX3. The Powkiddy RGB10MAX3 is a
handheld gaming device with a 720p 5.0 inch screen powered by the
Rockchip RK3566 SoC. It includes a Realtek 8723ds WiFi/BT module, 2 ADC
joysticks powered by a 4-way muxed ADC channel, and several GPIO
face buttons. There are 2 SDMMC slots (sdmmc1 and sdmmc3), 3 pwm
controlled LEDs, and the device includes 1GB of RAM.
