Add support for version 1.1 of the nfc nand flash controller which is on the i.mx25 soc.
Use CONFIG_NAND_MXC_V1 and CONFIG_NAND_MXC_V1_1 to differentiate between the two supported versions.
Add a define CONFIG_NAND_MXC_V1 to imx27lite board config.
Also factor out some soc specific nand geometry config into a new inline routine and a couple of defines: mxc_get_nfc_info IMX_NFC_IS_16BIT IMX_NFC_IS_2KPAGE
Added to imx-regs.h.

The 16-bit detection conflicts with http://lists.denx.de/pipermail/u-boot/2009-November/064139.html
Which way should I resolve the conflict? Or does one of you want to respin? I don't see 16BIT/2KPAGE/get_nfc_info defined for MX31... and does MX25 share MX27's imx-regs.h?
Magnus, can you test this patch on MX31?
I've now tested the patch and after adding an imx-regs.h for MX31 with the needed information the patch seems to work on i.MX31. Tested on the Litekit board with a small page NAND mounted.
A comment for John Rigby on the patch though: Is it really necessary to specify the version of the NAND controller in the board configuration file? As far as I know, once you select which i.MX-device to use U-boot already has the necessary information to derive the version of the NAND FC automatically.
