- Preserve the PROM IOMMU in order to allow OFW drivers to continue to
  work.
- Sanity check the parameters passed to the implementations of the
  pcib_{read,write}_config() methods. Using illegal values can cause
  no real harm but it doesn't hurt to avoid unnecessary data error
  traps requiring to flush and re-enable the level 1 caches.
