[PATCH v2 06/32] mtd: rawnand: fsl_elbc: convert driver to nand_scan()

[Miquel Raynal]

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().
