- Use bus_get_dma_tag() to obtain the parent DMA tag so dma(4) will
work when we start requiring this.
- Don't specify an alignment when creating our own parent DMA tag;
the supported DMA engines require no alignment constraint (f.e. the
LANCE child does though) and it's no inherited by the child DMA
tags anyway (which probably is a bug though).
- Fix whitespace nits.
