995291fbac Deal with the fact that PROM driver descriptors are allowed to have 
zero-length list of "standard addresses" by ignoring d_devbytes if
there are no addresses provided.  In these cases, the PROM will map
the device without our help.

cdfa209843 (1) kill ofnmmatch(); nothing used it (and it's not clear that 
anything _should_ use it).
(2) in the child properties check, also check for 'compatible,' and
    config_found() if the child has it.

044add4253 If we're using these devices on a big-endian CPU, byte swap the "count" 
field in the dp8390's packet header (because the dp8390 runs in little-endian
mode in these cases).  Inspired by an e-mail from Kazuki Sakamoto.

8a5023e38c After writing to the IOMMU flush registers, read something back from 
IOMMU control space to a flush register to drain internal write buffers (?).
This avoids utter lossage on some machines (SS4s & SS5s) where our caller
would see some of its local (`%lx') registers trashed. This is probably
caused by a silicon bug allowing interference on internal data paths..

09559070f7 * Do not remove ATN from the scsi bus if we have no messages queued but 
the target still is in MSG OUT phase. We still send a message (a NO_OP)
  in this case and the chip will remove ATN at the appropriate time.
  Using the RSTATN command here induces a "illegal command" in some
  chip revisions.

  This situation only occurs if the target rejects a previous (multi-byte)
  message early (by switching to MESSAGE IN and sending a MESSAGE REJECT)
  before the chip has completed the entire MSG OUT transfer. ATN will
  remain asserted, and the target returns to MESSAGE OUT phase.

* Account for the events above when reporting "DMA not completed"
  diagnostic messages.

* Stream-line the selection code a bit, and make the DMA setup code
  more like the MSG OUT & DATA XFER setup.
