    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.
