Various cosmetic and coding-style fixes

- Fix incorrect whitespace, indentation, and coding style in some places.

 - Drop '/**' Doxygen comments, we don't use Doxygen. Even if we would use
   it, the comments are useless as we don't have any Doxygen markup in there.

 - Use consistent vendor name spelling as per current website (NVIDIA,
   abit, GIGABYTE).

 - Use consistent / common format for "Suited for:" lines in board_enable.c.

 - Add some missing 'void's in functions taking no arguments.

 - Add missing fullstops in sentences, remove them from non-sentences (lists).
