riscv: Add Sipeed Maix support The Sipeed Maix series is a collection of boards built around the RISC-V Kendryte K210 processor. This processor contains several peripherals to accelerate 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; on-board usb-serial bridges; ports for cameras, displays, and sd cards; and ESP32 chips. Currently, only the Sipeed Maix Bit V2.0 (bitm) is supported, but the boards are fairly similar. Documentation for Maix boards is located at <http://dl.sipeed.com/MAIX/HDK/>. Documentation for the Kendryte K210 is located at <https://kendryte.com/downloads/>. However, hardware details are rather lacking, so most technical reference has been taken from the standalone sdk located at <https://github.com/kendryte/kendryte-standalone-sdk>.

riscv: Enable AI ram on K210 We just need to initialize all the clocks pre-reloc. The clock driver creates a bunch of devices, so we need to increase the pre-reloc malloc arena. Signed-off-by: Sean Anderson <seanga2@gmail.com>

riscv: Add support for SPI on Kendryte K210 This enables configs necessary for using SPI. The environment is saved to the very end of SPI flash. This is unlikely to be overwritten unless the entire flash is reprogrammed. This also supplies a default bootcommand. It loads an image and device tree from the first partition of the MMC. This is a minimal/least effort bootcmd, so suggestions (especially in the form of patches) are welcome. I didn't set up distro boot because I think it is unlikely that any general-purpose linux distros will ever be ported to this board.

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.
