marius 3584a5f5d1 - Merge the *_SET macros from fire(4) which generally print out the
register changes when compiled with SCHIZO_DEBUG and take advantage
  of them.
- Add support for the XMITS Fireplane/Safari to PCI-X bridges. I tought
  I'd need this for a Sun Fire 3800, which then turned out to not being
  equipped with such a bridge though. The support for these should be
  complete but given that it hasn't actually been tested probing is
  disabled for now.
  This required a way to alter the XMITS configuration in case a PCI-X
  device is found further down the device tree so the sparc64 specific
  ofw_pci kobj was revived with a ofw_pci_setup_device method, which is
  called by the ofw_pcibus code for every device added.
- A closer inspection of the OpenSolaris code indicates that consistent
  DMA flushing/syncing as well as the block store workaround should be
  applied with every BUS_DMASYNC_POSTREAD instead of in a wrapper around
  interrupt handlers for devices behind PCI-PCI bridges only as suggested
  by the documentation (code for the latter actually exists in OpenSolaris
  but is disabled by default), which also makes more sense.
- Add a workaround for Casinni/Skyhawk combinations. Chances are that
  this solves the crashes seen when using the the on-board Casinni NICs
  of Sun Fire V480 equipped with centerplanes other than 501-6780 or
  501-6790. This also takes advantage of the ofw_pci_setup_device method.
- Mark some unused parameters as such.
