- auxio cleanup and sbus support. - make GENERIC64 include GENERIC and set the 3 optoins it needs. suggested by hubert feyrer. - add a comment that we maybe should use the `bpp' driver, not the lpt, on the ebus because the `bpp' driver does DMA already. - ebus_attach_args got a member renamed

support for the UltraSPARC `Extension Bus' found on the PCI machines. the bus space/dma code is cloned from the PCI code to do the same thing which itself was cloned from the sbus bus space/dma code. the bus dma code is non-functional at this point.
