dt-bindings: update risc-v cpu properties
The Canaan Kendryte K210 SoC CPU cores are based on a rocket chip
version using a draft verion of the RISC-V ISA specifications. 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).
