since Micron MT29F2G08ABAEAWP's ecc error management:
|Description | Requirement
|Minimum required ECC | 4-bit ECC per 528 bytes
|Minimum ECC with internal ECC enabled | 4-bit ECC per 516 bytes (user data) +
8bytes (parity data)
to avoid unnecessary overheads related to bigger ecc calculations.
need choose to use fsl,use-minimum-ecc, else will run into ecc error.
