arm/mx2: define seperate imx_nand devices for imx21 and imx27
As the NFC controller has different addresses on imx21 and imx27 there are two different devices needed if not relying on the overloaded cpp macro NFC_BASE_ADDR. So some cpp magic is added to minimize code duplication. As obviously these two defines need different names, the name of the old device is #defined to the new one when building for only one of imx21 or imx27.
