Replace option BUSDMA_MI with LEGACY_BUS_DMA and provide the beginning
of a compatibility shim from the legacy bus_dma interface to the new
busdma/mi interface. The shim makes it possible (by intent) to switch
to busdma/mi without first having to port drivers to it. Use the new
LEGACY_BUS_DMA option to compile-in the actual legacy implementation
when *not* using busdma/mi and thus when now using the shim. Otherwise
the shim provides the implementation, which tends to do something else.

The shim needs fleshing out to be functional. In its current form it
merely allows LINT to build (for amd64).
