Dear Josh Wu,

- if CONFIG_SYS_NAND_ONFI_DETECTION is defined, driver will check NAND flash's
ecc minimum requirement in ONFI parameter.
a) if CONFIG_PMECC_CAP, CONFIG_PMECC_SECTOR_SIZE are defined. then use it. Driver will display a WARNING if the values are different from ONFI parameters.
b) if CONFIG_PMECC_CAP, CONFIG_PMECC_SECTOR_SIZE are not defined, then use the value from ONFI parameters. * If ONFI ECC parameters are in ONFI extended parameter page, since we are not support it, so assume the minimum ecc requirement is 2 bits in 512 bytes. * For non-ONFI support nand flash, also assume the minimum ecc requirement is 2 bits in 512 bytes.
- if CONFIG_SYS_NAND_ONFI_DETECTION is not defined, just use CONFIG_PMECC_CAP
and CONFIG_PMECC_SECTOR_SIZE.

resend: use braces around muti-line if/loop body.
v2 --> v3: use dev_err/info(host->dev) instead of dev_err/info(NULL). use MTDDEBUG() instead of pr_debug().
v1 --> v2: use dev_err/info to replace printk. fix typo mistake, that should use <= instead of use <.
