[PATCH 1/1] doc/riscv: Add description of disassembler options

[Nelson Chu]

This is okay from my side, thanks.  Btw, the privileged spec 1.9.1 support
was removed since binutils 2.43, so the option of objdump should also
remove it.  The linker only recognizes it and then reports a warning that
it may conflict with other spec versions.

Thanks
Nelson
