Fix the NAND size overflow issue.
When the total size of all NAND devices exceeds 4 GiB, the size will overflow. This patch tries to fix this. Note that we still have a problem when a single NAND device is bigger than 4 GiB: then the overflow would actually happen earlier, i. e. when storing the size in nand_info[].size, as nand_info[].size is an "u_int32_t".
