riscv: dts: canaan: Add basic device tree for K230 CanMV board Add initial dts for K230-CanMV powered by Canaan Kendryte K230 SoC, which has two RISC-V C908 cores, a big core with vector 1.0 extension and a small core without vector extension. This patch is basically comes from Linux Kernel [1] and it assumes u-boot is running on the big core. Additionally, bootctl and reboot nodes are added to support sysreset [2] and an clk_dummy node is added to satisfy dependencies for usb [3]. Currently, u-boot is booted by the vendor's u-boot-spl. To meet the requirements [4][5] of vendor's u-boot-spl for u-boot, a binman node with mkimage child node is added here, which will compress u-boot.bin with gzip and generate an image named "uboot" in the file u-boot-gz.img.
