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.
