[#2554] add 'iscman' references

The commands used were:
- find doc/sphinx/man -name '*.rst' | xargs grep -F '.. iscman' | cut -d ' ' -f 3 > /tmp/binaries
- for i in $(cat /tmp/binaries); do find doc/sphinx/arm -name '*.rst' | xargs sed -i "s/\`\`${i}\`\`/:iscman:\`${i}\`/g"; done

Manual adjustment was required in a few places to:
- extend title lines
- realign table lines
