    mtd: s3c2410: Fix compiler warnings
    
    Fixes the following warnings:
    ‘s3c2410_nand_correct_data’ defined but not used [-Wunused-function]
    ‘s3c2410_nand_enable_hwecc’ defined but not used [-Wunused-function]
    ‘s3c2412_nand_enable_hwecc’ defined but not used [-Wunused-function]
    ‘s3c2440_nand_enable_hwecc’ defined but not used [-Wunused-function]
    ‘s3c2410_nand_calculate_ecc’ defined but not used [-Wunused-function]
    ‘s3c2412_nand_calculate_ecc’ defined but not used [-Wunused-function]
    ‘s3c2440_nand_calculate_ecc’ defined but not used [-Wunused-function]
    
    The above functions are called only when CONFIG_MTD_NAND_S3C2410_HWECC
    is defined. Thus making them conditional.
