serengeti.diff and dtc-links.diff make serengeti find all of its devices
correctly.

serengeti.diff
- takes out the multiple links for the Opteron (they weren't working
correctly)
- adds the 8132 devices and makes them pci_a so they don't conflict with the
8111
- corrects the disabled flags (I think we should have a build error
somewhere when there are incorrect flags)
- moves the lpc device to the lpc bus
- adds back in the second Opteron

dtc-links.diff
- removes multiple link code.  I know someone could probably fix it, but
it's broken and not needed for now.
It made siblings that were bridges be multiple links on the same device.
That messed a lot of things up for Serengeti.  I think it could be changed
so that siblings with the same PCI identifier that are bridges become
multiple links.  It's ugly, though.

pci_match_v2.diff:
Even though Serengeti seems to work the same as v2, it still won't show
anything on the display.  The VGA device is not claiming the 0xa0000-0xc0000
address space.  Since SimNOW is a simulator, I trace the memory space to see
that the VGA writes are going to RAM.

I put this in to make the PCI config space bit-for-bit identical at VGA ROM
run.  It still doesn't work. :(  Any help would be appreciated.

Thanks,
Myles
