arm: dts: rockchip: add Radxa ROCK 4C+
Linux commit 246450344dad arm64: dts: rockchip: rk3399: Radxa ROCK 4C+
Add support for Radxa ROCK 4C+ SBC.
Key differences of 4C+ compared to previous ROCK Pi 4.
- Rockchip RK3399-T SoC
- DP from 4C replaced with micro HDMI 2K@60fps
- 4-lane MIPI DSI with 1920*1080
- RK817 Audio codec
Also, an official naming convention from Radxa mention to remove
Pi from board name, so this 4C+ is named as Radxa ROCK 4C+ not
Radxa ROCK Pi 4C+.
