arm64: dts: rockchip: Add devicetree for the ROC-RK3576-PC 



As the name implies, it is built around the RK3576 SoC with 4x Cortex-A72
cores, four Cortex-A53 cores and Mali-G52 MC3 GPU.

Storage options are EMMC, SD-Card, a 2242 M.2 slot and the possibility to
use UFS 2.0 storage.

Video Output options are a HDMI port, a DSI connector as well as Display-
Port via the TypeC connector (all of them not yet supported).

Networking options are a Low-profile Gigabit Ethernet RJ45 port with
Motorcomm YT8531 PHY as well as WiFi via an AMPAK AP6256 module.

USB ports on the board are 1x USB 3.0 port, 1x USB 2.0 port, 1x USB Type-C
and it comes with 40-pin GPIO header
