MXC: Add large page oob layout for i.MX31 NAND controller.
Import the large page oob layout from Linux mxc_nand.c driver.
The CONFIG_SYS_NAND_LARGEPAGE option is used to activate
the large page oob layout. Run time detection is not supported
as this moment.
This has been tested on the i.MX31 PDK board with a large
page NAND device.
