[PATCH 06/10] mtd: fix the wrong mtd->type for nand chip

[Huang Shijie]

Current code sets the mtd->type with MTD_NANDFLASH for both
SLC and MLC. So the jffs2 may supports the MLC nand, but in actually,
the jffs2 should not support the MLC.

This patch uses the nand_is_slc() to check the nand cell type,
and set the mtd->type with the right nand type.

After this patch, the jffs2 only can support the SLC nand.
