Subject: atmel_nand: use the definition: PMECC_OOB_RESERVED_BYTES instead magic number
X-Git-Tag: v2016.03-rc1~1^2~6

atmel_nand: use the definition: PMECC_OOB_RESERVED_BYTES instead magic number

As atmel_nand_ecc.h is sync with v4.1 kernel, which adds the
PMECC_OOB_RESERVED_BYTES. So use it in the driver.
