powerpc/85xx: fix NAND_CMD_READID read bytes number
when nand_get_flash_type() is called, it will read 8 bytes of ID instead of 5,
but the driver only read 5 bytes, so kernel will dump error messages like:
fsl-lbc ffe124000.localbus: read_byte beyond end of buffer
fsl-lbc ffe124000.localbus: read_byte beyond end of buffer
fsl-lbc ffe124000.localbus: read_byte beyond end of buffer
