arm64: dts: rockchip: add support for Firefly ROC-RK3399-PC-PLUS

ROC-RK3399-PC-PLUS is the board inside the portable Firefly Station P1 Geek
PC. As a redesign after the ROC-RK3399-PC, it uses DC-12V as power input
and spares a USB 3 host port. It is also equipped with a USB WiFi chip and
audio codec without the mezzanine board.

- Rockchip RK3399 SoC
- 4GB LPDDR4 RAM
- 16MB SPI-Flash
- eMMC slot
- TF card slot
- USB 3.0 Port x 1, USB 2.0 Port x 1, TypeC Port x 1
- HDMI
- Gigabit Ethernet
- WiFi: RTL8723DU
- Audio: ES8388
- Key: Recovery
- LED: WORK, DIY
- IR
