Random flashrom updates

 - Add explicit installation instructions in the README.

 - Code cleanups, coding style fixes, drop dead code.

 - Drop duplicate board listings from -L output (some boards were explicitly
   recorded in boards_ok[] _and_ implicitly via the board-enables table.

 - Add MS-xxxx numbers to MSI boards where we can find that info.

 - Fix typo, "K8T Neo2" should have been "K8T Neo2-F" actually, at least
   according to the comment of w83627thf_gpio4_4_raise_2e() which says
   "Suited for: MSI K8T Neo2-F".

Corresponding to flashrom svn r554.
