Log Message:
Rewrite at least the R{2,3}000 case for bus_dmamap_sync(), in hopes of
making performance of bus_dma drivers not completely suck on the DECstation.

XXX R4000 case is still abysmal, because some other data structure
modification is required to deal with the virtually-indexed R4000 cache.
