Wu, Josh a07d229497 ARM: at91: atmel_nand: add code to check the ONFI parameter ECC requirement 
1. 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.

2. if CONFIG_SYS_NAND_ONFI_DETECTION is not defined, just use CONFIG_PMECC_CAP
   and CONFIG_PMECC_SECTOR_SIZE.
