b2d59f4234 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.

cbbdf2367e Add detach, shutdown, suspend and resume methods. The latter two are
not really tested, but are derived from the original NetBSD version.

305f2c0632 - Convert to use bus_dmamap_load_mbuf().
- remove DPRINTF(), there is a CTR*() for any of them, and KTR is
  far more useful to debug this driver.
- some cleanups; remove some unused code and definitions.

0d80b9bd88 In some cases, RX descriptors that are signalled to have been completed
by the hardware are still marked as owned. Handle this by installing a
timeout handler to collect this descriptor to avoid having received
packets remain unhandled until the next one arrives.
