MX25 has a different version of the fsl_nfc
flash controller known as version 1.1.

Add support to the nand_spl fsl_nfc driver

Versioning differs from mainline mxc kernel driver
no consensus yet on if the naming here and in
Redboot or the kernel is "correct".

This patch adds the NAND SPL framework needed to boot i.MX31 boards
from NAND.

It has been tested on a i.MX31 PDK board with large page NAND. Small
page NANDs should work as well, but this has not been tested.

Note: The i.MX31 NFC uses a non-standard layout for large page NANDs,
whether this is compatible with a particular setup depends on how
the NAND device is programmed by the flash programmer (e.g. JTAG
debugger).

The patch is based on the work by Maxim Artamonov.
