[bug#63071] [PATCH] gnu: Add emacs-riscv-mode

[Gabriel Wicki <gabriel@erlikon.ch>]

Hello!

I hope this email finds you in a state of well-being!

I've come around to package this small little emacs-package which is
supposed to aid RISC-V assembly development.  Please let me know if I
can fix/improve/adjust anything with the patch.

It is based on commit 8c5ba69d6e9e4b1b9d6b5e9cd28859b19e8e180c


Best wishes,
gabber
