[PATCH v2 01/53] mtd: nand: allow to set only one of ECC size and ECC strength from DT

Currently, it is valid to specify both "nand-ecc-step-size" and "nand-ecc-strength", but not allowed to set only one of them. This requirement has a conflict with "nand-ecc-maximize"; this flag is used when you want the driver to choose the best ECC strength. If "nand-ecc-maximize" is set,
