Fix gcc build error while CONFIG_MTD_NAND_ECC_SW_BCH
is set to module:
drivers/mtd/nand/raw/nand_base.o: In function `nand_cleanup':
(.text+0xef6): undefined reference to `nand_bch_free'
drivers/mtd/nand/raw/nand_base.o: In function `nand_scan_tail':
nand_base.c:(.text+0xa101): undefined reference to `nand_bch_calculate_ecc'
nand_base.c:(.text+0xa120): undefined reference to `nand_bch_correct_data'
nand_base.c:(.text+0xa269): undefined reference to `nand_bch_init'
CONFIG_MTD_NAND_ECC_SW_BCH should not be set to M,
because MTD_RAW_NAND need it while linked.
