radxa-zero-3{e|w}: add

The Radxa ZERO 3{e|w} are ultra-small, high-performance single board computers
based on the Rockchip RK3566, with a compact form factor, and rich interfaces.

	http://radxa.com/products/zeros/zero3e/
	http://radxa.com/products/zeros/zero3w/

common tech specs:
- Rockchip RK3566 (4x Arm Cortex-A55 @ 1.6GHz)
- Arm Mali-G52-2EE (OpenGL ES 1.1/2.0/3.0/3.1/3.2, Vulkan 1.1, OpenCL 2.0)
- LPDDR4 RAM (1/2/3/8 GB)
- µSD
- 1x USB 2.0 Type C OTG, 1x USB 3.0 Type C Host
- 1x µHDMI (1080p @ 60fps)
- 1x MIPI CSI camera port
- colour-coded 40-pin GPIO (uart, spi, i2c, pcm/i2s, pwm, gpio)
- 72mm x 30mm

Radxa ZERO 3e specific tech specs:
- GbE

Radxa ZERO 3w specific tech specs:
- optional onboard eMMC (8/16/32/64 GB)
- IEEE 802.11 b/g/n/ac/ax(WiFi6), BT5.4 with BLE

NOTE: currently support for this board requires a U-Boot fork for the
bootloader, and linux-next for the kernel. Support will probably come in linux
kernel 6.11-ish, at which point U-Boot will then use that kernel's device tree
which means U-Boot support will come after the release of whichever kernel
includes support for this board.
