mx28evk: Introduce a new target for saving env vars to NAND

Browse Source 
Introduce 'mx28evk_nand' target for saving environment variables into NAND.

The mx28evk board does not come with a NAND flash populated from the
factory. It comes with an empty slot (U23), which allows the insertion of a
48-pin TSOP flash device.

Tested with a K9LBG08U0D.

Environment Storage
-------------------
There are two targets for mx28evk:
"make mx28evk_config" - store enviroment variables into MMC
or
"make mx28evk_nand_config" - store enviroment variables into NAND flash
Choose the target accordingly.
Note: The mx28evk board does not come with a NAND flash populated from the
factory. It comes with an empty slot (U23), which allows the insertion of a
48-pin TSOP flash device.
Follow the instructions from doc/README.mx28_common to generate a bootable SD
card.
