MFC: am7990.c 1.4; am79900.c 1.4; if_le_ledma.c 1.3; if_le_pci.c 1.5, 1.6;
     lance.c 1.3, 1.4; lancevar.h 1.3

- Use our own callout instead of if_slowtimo() for driving lance_watchdog()
  in order to avoid races accessing if_timer.
- Use bus_get_dma_tag() to obtain the parent DMA tag so le(4) works on
  platforms requiring this.
- Remove BUS_DMA_WAITOK from bus_dma_tag_create() invocations as it's
  no valid flag there.
- For setting the port PCnet chips must be powered down or stopped and
  unlike documented may not take effect without an initialization. So
  don't invoke (*sc_mediachange) directly in lance_mediachange() but
  go through lance_init_locked(). It's suboptimal to impose this for
  all chips but given that besides the affected PCI bus front-end the
  only other front-end which supports media selection is and likely
  ever will be the 'ledma' front-end I see not enough reason to break
  the in-driver API for this (though one could argue both ways here).
