dt-bindings: add Canaan boards compatible strings
Introduce the file riscv/canaan.yaml to document compatible strings related to the Canaan Kendryte K210 SoC. The compatible string "canaan,kendryte-k210" used to indicate the use of this SoC to the early SoC init code is added. This new file also defines the compatible strings of all supported boards based on this SoC.
