Final pass at having devices use their bus parent for dma tags. The
remaining drivers that haven't been converted have various problems or complexities that will be dealt with later. This list includes: hptrr, hptmv, hpt27xx - device aggregation across multiple parents drm - want to talk to the maintainer first tsec, sec - Openfirmware devices, not sure if changes are warranted fatm - Done except for unused testing code usb - want to talk to the maintainer first ce, cp, ctau, cx - Significant driver changes needed to convey parent info There are also devices tucked into architecture subtrees that I'll leave for the respective maintainers to deal with.
