To avoid any confusion with CPU cores using stable specifications, add the compatible string "canaan,k210" for this SoC CPU cores. Also add the "riscv,none" value to the mmu-type property to allow a DT to indicate that the CPU being described does not have an MMU or that it has an MMU that is not usable (which is the case for the K210 SoC).
