mtd: s3c2410_nand: Add config option to disable hw ecc at runtime
This patch adds a flag to the s3c2410_nand platform data, which configures whether hardware ecc is used for that chip. Currently hardware ecc is used if it was compiled into the kernel. But if you want to build a kernel which runs on multiple devices you might have a configuration where you have devices which require hw ecc as well as devices which want software ecc.
