  Log:
  In pcib_alloc_resource() check if the resource allocation request is
  for the VGA I/O or memory ranges, when it's not within the default
  ranges decoded by the bridge. When allocation for VGA addresses is
  attempted, check that the bridge has the VGA Enable bit set before
  allowing it.
  As such, newbusified VGA drivers can allocate their resources when
  the VGA adapter is behind a PCI-to-PCI bridge.
