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.
