Drop src/config alltogether

Drop src/config alltogether

- drop two "newconfig" based files
- drop two obsolete doxygen config files and check
  in our latest Doxyfile.coreboot (that has been
  used to build coreboot online documentation since
  2005 or so)
- move two i386 specific linker scripts to src/arch/i386
