[PATCH v3 06/33] mtd: rawnand: fsl_ifc: convert driver to nand_scan()

Two helpers have been added to the core to make ECC-related configuration between the detection phase and the final NAND scan. Use these hooks and convert the driver to just use nand_scan() instead of both nand_scan_ident() and nand_scan_tail().
