Add two buildroot configuration files to build a minimal Linux environment for the Sipeed MAIX Bit board. The configurations are: * sipeed_maix_bit_defconfig: Build a bootable kernel image with an embedded initramfs root file system. The image built can be flashed to the board as is and does not require a boot loader. This configuration uses the tiny busybox configuration defined in board/canaan/k210-soc/busybox-tiny.config. * sipeed_maix_bit_sdcard_defconfig: Build a kernel image with a root file system on the SD card and using U-Boot as the boot loader. This uses the default busybox minimal configuration. Both configurations also enable the python-kflash and pyserial-miniterm host tools for flashing image files to the board and opening a terminal console. The readme.txt file documents how to build and boot the Sipeed MAIX-Bit board with these configurations.
