flash_erase: check the nand type
Now, the MTD_NANDFLASH stands for SLC nand, and the MTD_MLCNANDFLASH stands for the MLC nand. This patch includes the stdbool.h, and changes the "isNAND" to boolean type, and checks the right nand type for the MLC and SLC nand. If the user wants to format a MLC nand for JFFS2, we will print out a message to warn him, and exit right now.
