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 Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Acked-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
