Revision 705

Right now, our Kconfig files in the mainboard/ directory in the v3 tree 
are not exactly in the best shape.
- MAINBOARD_NAME is claimed to be the mainboard name, but it is used 
  exclusively as mainboard directory.
- MAINBOARD_NAME is set in mainboard/$VENDOR/$BOARD/Kconfig to
  $VENDOR/$BOARD, but mainboard/$VENDOR/Kconfig already hardcodes
  $VENDOR/$BOARD as board path.
- MAINBOARD_NAME has a help text which will never be displayed to
  the user.

The diffstat is encouraging: A total of 200 lines have been
removed completely.

Per-board Kconfig files have been deleted, the remnants making sense
have been merged into per-vendor Kconfig files and the never-shown help
texts have been removed.

If there are ever some real per-board options and not just tricks to
make the makefiles behave, we can resurrect the per-board Kconfig files.
