Fix sata_via write errors on PATA drive connected to VT6421
I think that I've found and fixed the problem. There is a copy/paste bug in vt6421_set_dma_mode() function which causes wrong values to be written to PATA_UDMA_TIMING register. This patch fixes a copy/paste bug that breaks DMA modes on VT6421 PATA port.
