   * Name: board_app_initialize
   *
   * Description:
   *   Perform application specific initialization.  This function is never
   *   called directly from application code, but only indirectly via the
   *   (non-standard) boardctl() interface using the command BOARDIOC_INIT.
   *
   * Input Parameters:
   *   arg - The boardctl() argument is passed to the board_app_initialize()
   *         implementation without modification.  The argument has no
   *         meaning to NuttX; the meaning of the argument is a contract
   *         between the board-specific initialization logic and the
   *         matching application logic.  The value could be such things as a
   *         mode enumeration value, a set of DIP switch switch settings, a
   *         pointer to configuration data read from a file or serial FLASH,
   *         or whatever you would like to do with it.  Every implementation
   *         should accept zero/NULL as a default configuration.
   *
   * Returned Value:
   *   Zero (OK) is returned on success; a negated errno value is returned on
   *   any failure to indicate the nature of the failure.
