The version 2.0 controller has the ECC status registers at a different location to the previous versions. Correct the fsl_ifc_nand structure so that the ECC status can be read from the correct location for both version 1.0 and 2.0 of the controller.

It will be used for ARM-based SoC as well. This patch moves the driver to driver/memory and fix the header file includes.
