John-Mark Gurney 378f231e7d add a newbus method for obtaining the bus's bus_dma_tag_t... This is ... required by arches like sparc64 (not yet implemented) and sun4v where there are seperate IOMMU's for each PCI bus... For all other arches, it will end up returning NULL, which makes it a no-op... Convert a few drivers (the ones we've been working w/ on sun4v) to the new convection... Eventually all drivers will need to replace the parent tag of NULL, w/ bus_get_dma_tag(dev), though dev is usually different for each driver, and will require hand inspection...
