pata_pdc202xx_old: Fix crashes with ATAPI
The PDC202xx older devices do not support ATAPI DMA via the usual
interfaces. What documentation I have isn't sufficient to support DMA and
it isn't clear if the Windows drivers do this or it is possible at all.
(Neither do the drivers/ide old drivers)
So turn it ATAPI DMA off, these are disk optimised controllers.
