ata_piix: fix pio/mwdma programming
Fix various bugs in pio/mwdma mode programming. * Control bits in the timing register wasn't cleared properly while programming PIO mode. * MWDMA mode programming cleared the wrong part of control bits. * MWDMA mode programming cleared udma_mask even when the controller doesn't support UDMA.
