[PATCH 11/12] of: mtd: drop support for NAND_ECC_SOFT_BCH as "soft_bch" mapping

[PATCH 11/12] of: mtd: drop support for NAND_ECC_SOFT_BCH as "soft_bch" mapping

[Rafał Miłecki]

There isn't any difference between handling NAND_ECC_SOFT and
NAND_ECC_SOFT_BCH now. What matters is the new field called "algo".
Please note we're keeping backward DT compatibility. We are still
treating "soft_bch" value as the one setting Hamming algorithm, it's
just handled in of_get_nand_ecc_algo now.

This series is getting rid of of_mtd{.c,.h}, so I'll move those changes
directly into nand_base.c when applying.
