board: rockchip: Add ArmSoM Sige5

ArmSoM-Sige5 adopts the second-generation 8nm high-performance AIOT
platform Rockchip RK3576, with a 6 TOPS computing power NPU and support
for up to 16GB of large memory. It supports 4K video encoding and
decoding, offers rich interfaces including dual gigabit Ethernet ports,
WiFi 6 & BT5, and various video outputs.

Features tested on a ArmSoM Sige5 v1.1:
- SD-card boot
- eMMC boot
- Ethernet
- PCIe NVMe
