arm64: dts: cix: Add OrangePi 6 Plus board support

OrangePi 6 Plus adopts CIX CD8180/CD8160 SoC, built-in 12-core 64-bit
processor + NPU processor,integrated graphics processor, equipped with
16GB/32GB/64GB LPDDR5, and provides two M.2 KEY-M interfaces 2280 for NVMe
SSD,as well as SPI FLASH and TF slots to meet the needs of fast read/write
and high-capacity storage
