Stacey Sheldon dc4aa07a32 board_hw_defs: factor out board-specific hw config definitions
Board specific HW configuration is now collected in a single .c
file for each board.  This HW configuration is #include'd into
the FW, BL and BU builds for each board.

These new .c files are found in:
  flight/board_hw_defs/<board_name>/board_hw_defs.c

Parts of this information were previously duplicated between
the BL and FW builds.  This commit cleans up the duplication.

Using a #include on a .c file is a bit ugly but it allows us
to ensure that all of the symbols in the board_hw_defs.c file
are *ONLY* used in the PIOS_Board_Init() function for each
software build.
