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.
