mtd: nand: fix the wrong mtd->type for nand chip
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 supports the SLC nand.
The side-effect of this patch:
Before this patch, the ioctl(MEMGETINFO) can only return with the
MTD_NANDFLASH; but after this patch, the ioctl(MEMGETINFO) will
return with the MTD_NANDFLASH for SLC, and MTD_MLCNANDFLASH for MLC.
So the user applictions(such as mtd-utils) should also changes a little
for this.
