NAND: Add 16bit NAND support for the NDFC
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.
