If the memory range of the machine is such that no bouncing is necessary,
...
or if the device is capable of 32-bit DMA (specified by ISABUS_DMA_32BIT),
clear the map's bounce threshold at map creation time.

Sync w/ i386 port:
...
Optimize the ISA DMA map load somewhat; don't traverse the buffer twice.
Instead, just attempt to do a normal load first. If we exceed the bounce
threshold or the number of segments, then we bounce the transfer.

and allow more than one synchronization operation to be specified in
a single call. Dissallow mixing of PRE and POST operations.
