    This patch adds support for 16 bit NAND devices attached to the
    NDFC on ppc4xx processors. Two config entries were added:
    
      CONFIG_SYS_NDFC_16        - Setting this tells the NDFC that a
    			      16 bit device is attached.
      CONFIG_SYS_NDFC_EBC0_CFG  - This is for the External Bus
    			      Controller configuration register.
    
    Also, a new ndfc_read_byte() function was added which does not
    first convert the data to little endian.
    
    The NAND SPL was also modified to do 16bit bad block testing
    when a 16 bit chip is being used.
