mtd: nand: add more comment for MTD_NANDFLASH/MTD_MLCNANDFLASH
In current code, the MTD_NANDFLASH is used to represent both the SLC and MLC. It is confusing to us. By adding an explicit comment about these two macros, this patch makes it clear that: MTD_NANDFLASH : stands for SLC NAND, MTD_MLCNANDFLASH : stands for MLC NAND (including TLC).
