To be used with the sysinfo command, revision values must be considered
as integers, not chars as some boards will implement BOARD_REVISION_*
and might use numbers greater than 9.

Is there really no way to do this with single snprintf() call instead of
two snprintf() calls ?
I find it more readable like this, as opposed to have an snprintf in the if and
one in an else block for each switch case.
I think I don't get it here -- why can't this be done with single
snprintf() ? I mean, the revision is always set anyway.
