- Register the generic implementations for the device shutdown, suspend

  and resume methods so these events propagate through the device driver
  hierarchy.
- In dma(4) enable the chaining of the DMA engine interrupt handler for
  the LANCE devices via a dma_setup_intr(). This was commented out before
  as I was unsure whether I'd use it but this is probably cleaner than
  fiddling with the DMA engine interrupt in the LANCE driver directly.
- In ebus_setup_dinfo() free 'intrs' instead of 'reg' twice in case
  setting up a child fails due to routing one of its interrupts fails. [1]
