nand/denali: change read_status function method
In mtd->write, Denali controller will use MODE_11 mode to read NAND flash status, then return back to MODE_1O mode to do page write. Here comes a bug for this kind of using, sometimes controller will not write data to NAND and just return a good interrupt to tell driver writing work is done. The data in this page is all 0xff and this page can not be written again. The reason is unknow. So read Denali controller register WRITE_PROTECT to get NAND status instead.
