This patch refactors a lot of the existing doxygen within libbsp/arm/lpc32xx. Much of this refactoring was just renaming of existing groups to conform to a more consistent naming structure. With the addition of a doxygen header for tm27.h, all files within lpc32xx belong to doxygen group now. lpc32xx should be used a reference for adding doxygen to other bsps.
