mtd: mtd: drop NAND_ECC_SOFT_BCH enum value
This value should not be part of nand_ecc_modes_t as it specifies algorithm not a mode. We successfully managed to introduce new "algo" field which is respected now. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com>
