mtd: rawnand: fix build dependency
When enabling CONFIG_MTD_NAND_ECC_SW_BCH as a module, the
MTD_NAND_ECC_SW_BCH depends on MTD_NAND, but the module controlled by
MTD_NAND links against the module controlled by MTD_NAND_ECC_SW_BCH.
This leads to the following link failure.
aarch64-linux-gnu-ld: drivers/mtd/nand/raw/nand_base.o: in function `nand_cleanup':
../drivers/mtd/nand/raw/nand_base.c:5886: undefined reference to `nand_bch_free'

Rework CONFIG_MTD_NAND_ECC_SW_BCH from tristate to bool,
and then link the nand_bch.o file into nand.ko if its enabled.
