Log Message:
Change the way that DMA map syncs are done.  Instead of remembering
the virtual address for each DMA segment, just cache a pointer to the
original buffer/buftype used to load the DMA map, and use that.  This
lets us shrink the bus_dma_segment_t down from 12 bytes to 8, and the
cache flushing is also more efficient.

Tested on an i80321 -- changes to others are mechanical.
