Log Message:
whole bunch of changes:
- merge IOMMU DVMA code from sbus/psycho into iommu.c.  this code was
  identical and a few minor inconsistencies had crept in.  this way
  keeps them all in sync.
- with this code gone from psycho, merge the psycho.c and psycho_bus.c
  files.  same with ebus/ebus_bus.c.  delete the _bus.c files.
- add a _ds_boundary member to the dma segment structure, so that later
  dma mappings can find this value.
- set _ds_boundary in machdep.c:_bus_dmamem_alloc().
- kill much dead code.
