Implement tested/untested status for board enables

The message printing code greatly exceed the 80 character limit. I can
reformat it on request to obey the limit.

Intended behaviour:
on untested boards an explanation of that status is printed and the board
enable code is not run, unless the option "boardenable=force" has been
passed to the internal programmer.

Corresponding to flashrom svn r919.
