arm64: dts: rockchip: Add Radxa ZERO 3W/3E

The Radxa ZERO 3W/3E is an ultra-small, high-performance single board
computer based on the Rockchip RK3566, with a compact form factor and
rich interfaces.

The ZERO 3W and ZERO 3E are basically the same size and model, but
differ only in storage and network interfaces.

- eMMC (3W)
- SD-card (both)
- Ethernet (3E)
- WiFi/BT (3W)

Add initial support for eMMC, SD-card, Ethernet, HDMI and USB.
