Sync with other *BSDs:
>From OpenBSD's rev. 1.93:
> to quote from the gospel of bus_dma.9:
>
> Synchronization operations are expressed from the perspective of the host
> RAM, e.g., a device -> memory operation is a READ and a memory -> device
> operation is a WRITE.
>
> the status block that the isr reads is written to by the device.
> the chip writes to memory, it is therefore a READ.
>
> this also adds the preread sync when the map is set up and the postread
> sync when the map is torn down for better symmetry. there are probably
> more issues like this in the code, but this is a start.
