Add list with DMI chassis types

Half a dozen hardcoded strcmp() don't make sense if we need a
chassis-type list anyway once we merge the internal DMI decoder. Provide
and array of the most interesting chassis types and annotate them with
laptop/non-laptop status. Match the dmidecode chassis type against the
strings in the array.

Corresponding to flashrom svn r1182.
