The baseline for the RISC-V privileged ISA is version 1.10. Using
features from newer versions of the privileged ISA requires the
supported version to be reported by platform firmware, either in the ISA
string (where the binding already accepts version numbers) or in the
riscv,isa-extensions property. So far two newer versions are ratified.
