Thomas Moestl aaa160f357 bus_dmamap_sync() overhaul:
- Remove NetBSD-style or-ed together BUS_DMASYNC operations, in some
  cases relaxing the (intended) syncing operation a bit.
- Add syncs before reading the descriptor rings.
- Try to combine syncs where possible to avoid overhead.
- Sync all maps before unloading them.
