Update bus_dma to the better codebase found on almost all other platforms,
where the common part to all bus_dmamap_load*() functions is implemented in
in an internal load_buffer routine.
This allows the xbridge-specific dma code to only provide this function,
instead of three; and this also brings us a working bus_dmamap_load_uio()
on all supported sgi machines, which in turns make crpyto(4) devices really
work. Tested with hifn(4).
