[MTD] [NAND] S3C2410 Fix previous nFCE suspend save patch
Commit 03680b1e00d146df718c8a4eac34438566b70c85 incorrectly was assuming S3C2410_NFCONF was being used to select the NAND chip. Fix this error by ising the sel_reg. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
