[PATCH v5 2/2] arm64: dts: rockchip: add support for Radxa ROCK Pi E v3.0

[FUKAUMI Naoki <naoki@radxa.com>]

Radxa ROCK Pi E v3.0 is a compact networking SBC[1] using the Rockchip
RK3328 chip that ships in a number of RAM/eMMC/WiFi/BT configurations:

- Rockchip RK3328 SoC
- Quad A53 CPU
- 512MB/1GB/2GB DDR4 RAM
- 4/8/16/32GB eMMC
- Micro SD Card slot
- WiFi 4 and BT 4, or WiFi 5 and BT 5
- 1x 1000M Ethernet supporting PoE with add‑on PoE HAT
- 1x 100M Ethernet
- 1x USB 3.0 Type-A port (Host)
- 1x 4-ring 3.5mm headphone jack
- 40 Pin GPIO header
