Add support for Zicbop found on SpacemiT K1/M1 CPU

Currently there will be an error:

[ERROR]: parse_multi_letter_extension: Unknown multi-letter extension: zicbop

FYI: https://github.com/riscv/riscv-CMOs/blob/master/cmobase/Zicbop.adoc

Thanks for the report. I prefer to keep small patches like this as issues rather than PR. Can you confirm the latest patch works as expected? A picture would also be greatly appreciated, thanks!

@Dr-Noob yes, it works.

Nice. If you post the output of cpufetch --verbose in a new issue we can try fixing the unkown SoC and microarchitecture 👍
