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