since bus_mem_subregion() can return failure, don't even bother to try
...
to handle the case where subregion offset isn't a multiple of 8.

gross hack to get around the fact that there are currently devices with
...
common back-ends that live on multiple very-different busses (e.g. PCI and
TC), which need bus-specific DMA mapping support. As a nice side effect,
this will allow the especially nasty (vtophys(va) | 0x40000000) expressions
to go away in favor of less nasty bus-specific function calls.

add wbflush() calls in strategic places. These really shouldn't be
...
here, and there should be a generic 'bus' interface to do memory
read/write barriers.

TurboChannel bus_mem_* functions. bus_mem_{read,write}_8, and
...
bus_mem_read_{1,2} are not yet supported for sparse space.
