The omap_gpmc allows switching ecc at runtime. Since the NAND_SUBPAGE_READ flag is only set, it is kept when switching to hw ecc, which is not correct. This leads to calling chip->ecc.read_subpage which is not a valid pointer. Therefore clear the flag when switching ecc so reading in hw mode works again.
