* Cleanup TQM5200 board configurations:

  - make highboot configurations use environment at high end, too,
    to avoid flash fragmentation
  - always use redundand environment
  - don't enable video code for modules without graphics controller
  - provide useful (though different) mtdparts settings
  - get rid of CONFIG_CS_AUTOCONF which was always set anyway

* Extend mkconfig tool to print more useful target name
