[MTD] [NAND] S3C2410: Move to using platform device table
Commit 57fee4a58fe802272742caae248872c392a60670 added an method to specify the platform device compatibility by using an id-table instead of registering multiple drivers. Move the S3C24XX NAND driver to using this ID table. Signed-off-by: Ben Dooks <ben-linux@fluff.org> CC: Eric Miao <eric.miao@marvell.com>
