arm64: dts: rockchip: add support for Firefly ROC-RK3328-PC

ROC-RK3328-PC is the board inside the portable Firefly Station M1
Geek PC. As a redesign after the ROC-RK3328-CC, it uses TypeC as
power input and OTG port, embedded with eMMC 5.1 storage and a
SDIO WiFi/BT chip (RTL8723DS).

- Rockchip RK3328 SoC
- 2/4GB LPDDR3 RAM
- 16/32/64/128GB eMMC 5.1
- TF card slot
- USB 3.0 Port x 1, USB 2.0 Port x 1, TypeC Port x 1 (Power/OTG)
- HDMI
- Gigabit Ethernet
- WiFi: RTL8723DS
- Audio: RK3328
- Key: Power, Reset, Recovery
- LED: POWER, USER
- IR
