riscv: dts: spacemit: Add OrangePi RV2 board device tree
Add initial device tree support for the OrangePi RV2 board [1]. The board is described as using the Ky X1 SoC, which, based on available downstream sources and testing, appears to be identical or very closely related to the SpacemiT K1 SoC [2]. The device tree is adapted from the OrangePi vendor tree [3], and similar integration can be found in the Banana Pi kernel tree [4], confirming SoC compatibility. The main difference with the current Banana Pi BPI-F3 tree is that status led is using GPIO_ACTIVE_LOW. This minimal device tree enables booting into a serial console with UART output and a blinking LED.
