Be more refined regarding DMI chassis types

Browse Source 
We had broken laptops in the past that were not detected as such because
their DMI chassis-type was either undefined/out-of-spec, or set to
'other' or 'unknown'.

this patch tries to mitigate this problem as follows:
- if the DMI chassis-type clearly identifies the system as
  laptop/notebook/mobile platform then nothing changes: the user gets
  the laptop warning without a hint to the force switch.
- if the DMI chassis-type is not specific enough, we warn the user
  similarly, but tell them the switch.

to reduce the number of false positives i have added a few new
chassis types that we have encountered in the last months to the list.

Corresponding to flashrom svn r1390.
