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+.

Changes for v3:
- updated commit message
- include sdhci in aliases
- add i2s2
- add sdmmc cd-gpios
- use rk3399-t-opp.dtsi
Changes for v2:
- s/vcc-sys/vcc5v0-sys-regulator
- used proper node name 'regulator' for syr828 regulator nodes.
- fix line wrapping.
