Log:
bus_dmamap_sync() overhaul:
- Remove NetBSD-style or-ed together BUS_DMASYNC operations, in some
cases relaxing the (intended) syncing operation a bit.
- Stop pretending that that we can sync part of a dmamap: replace the
GEM_CDTXSYNC and GEM_CDRXSYNC macros with GEM_CDSYNC to sync the
complete control map, and combine syncs wherever possible to avoid
the overhead.
- Sync all maps before unloading them.
- Remove a few syncs which should be unnecessary.
