mtd: denali: kill the NAND_MAX_PAGESIZE/NAND_MAX_OOBSIZE
This patch kills the NAND_MAX_PAGESIZE/NAND_MAX_OOBSIZE by the following way: 1.) change the @buf field of nand_buf{} from an array to a pointer. also remove the DENALI_BUF_SIZE macro. 2.) Before we call the nand_scan_ident, we allocate a temporary buffer whose size is PAGE_SIZE. 3.) After we finish the nand_scan_ident, we have already getten the page size and oob size. We will allocate the right buffer size again.
