riscv: Add device tree for K210 and Sipeed Maix BitM Where possible, I have tried to find compatible drivers based on the layout of registers. However, many devices remain untested. All untested devices have been left disabled, but some tentative properties (such as compatible strings, and clocks, interrupts, and resets properties) have been added.

k210: use the board vendor name rather than the marketing name "kendryte" is the marketing name for the K210 RISC-V SoC produced by Canaan Inc. Rather than "kendryte,k210", use the usual "canaan,k210" vendor,SoC compatibility string format in the device tree files and use the SoC name for file names. With these changes, the device tree files are more in sync with the Linux kernel DTS and drivers, making uboot device tree usable by the kernel.
