This adds NAND Flash Controller (NFC) support for the Vybrid tower system (TWR-VF65GS10). Full 16-Bit bus width is supported. Also an aditional config vf610twr_nand is introduced which gets the environment from NAND. However, booting U-Boot from NAND is not yet possible due to missing boot configuration block (BCB).
