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.

-Several of the Sipeed Maix series of boards cotain the Kendryte K210 processor,

-neural network processing and other "ai" tasks. This includes a "KPU" neural
-network processor, an audio processor supporting beamforming reception, and a
-digital video port supporting capture and output at VGA resolution. Other
-peripherals include 8M of SRAM (accessible with and without caching); remappable
-pins, including 40 GPIOs; AES, FFT, and SHA256 accelerators; a DMA controller;
-and I2C, I2S, and SPI controllers. Maix peripherals vary, but include spi flash;

 Currently, only the Sipeed MAIX BiT V2.0 (bitm) and Sipeed MAIXDUINO are
 supported, but the boards are fairly similar.
