Allows a board config to override the number of partitions and names 

A board_config may define BOARD_HAS_MTD_PARTITION_OVERRIDE to
   uses it's own number of partitions and names.

   If a BOARD_HAS_MTD_PARTITION_OVERRIDE is not defined
   the hardcoded original values of fs/mtd_params &
   /fs/mtd_waypoints are used.

on an mtd device.
