drivers: rkflash: Add ecc_strength value

Browse Source 
SPI Nand support these flowing ECC status:
1.ECC OK.
2.ECC bits flip is correctable and not reach it's ecc_strength.
3.ECC bits flip is correctable and reach it's ecc_strength.
4.ECC failed.

Case2/3 rely on ecc_strength value, or will be set as ECC ok although
it's accept.
