If a device only has 32-bit BARs it's generally not capable of handling
64-bit DMA addresses and we can point and laugh at the card.
mptsas is a driver that uses dma_get_required_mask() to determine a
"suitable" DMA mask -- but under Xen dma_get_required_mask() may return
the wrong mask since it only gets the physical RAM range and not machine
addresses.
