The Linux kernel parses the ISA extensions from "riscv,isa" DT property. It used to parse only the single letter base extensions until now. A generic ISA extension parsing framework was proposed[1] recently that can parse multi-letter ISA extensions as well. Generate the extended ISA string by appending the available ISA extensions to the "riscv,isa" string if it is enabled so that kernel can process it.
