Add the default configuration for SpacemiT K3 boards, using the Pico-ITX device tree as the default.
Configure U-Boot to run in RISC-V supervisor mode and enable the platform clock, reset, GPIO, pinctrl, I2C, PMIC and regulator drivers. Also configure the memory layout, debug UART and basic filesystem commands required to boot on the platform.
