Device attachment for the real-time clock.
Merge some fixes from clock.c, revision 1.23.
Use new RTC attachment.
Convert hil to standard device attachment.
Update for new RTC and HIL attachments.
Add more fields to hardware structs.
Add memory allocation for various data structures.
add Trident 4DWAVE based (4DWAVE DX/NX,SiS 7018,ALi M5451) PCI audio driver
add autri (Trident 4DWAVE based AC'97 audio)
White space nit.
Fix typo (etc/config -> etc.config)

* Add a callback to the front-end for the 33c93 driver to reset
  the controller/SCSI bus.
* Implement controller/SCSI bus reset on SGI HPC3 SCSI using the
  "channel reset" bit in the SCSI DMA channel control register.
Correct operation of non-pseudo-DMA mode.  Used on 660 & 840 AV models.
From Takeshi Shibagaki<ie9t-sbgk@asahi-net.or.jp>.
note linksys prism2 support.
* Clean up HPC autoconfiguration a little.  Pass device register and
  DMA register offsets, as well as IRQ, to children.  Use direct
  config.  Use machine type/subtype to determine which devices are
  present.
* Add support for the second SCSI controller on the Indigo2.
Rewrite bus stuff with method table in the bus tags.
Tweak for HPC autoconfig changes.
