Fix build errors by selecting DM_BUFIO.
Fix Kconfig entry formatting by using tabs instead of spaces,
using "help" instead of "---help---", and
indenting help text with one additional space.
Fixes these build errors:

Thanks, fine with me for the most part.
We mainly use '---help---' for dm/md though, so lets's keep it. Mike?
