John Baldwin 0070c94be9 Add two tunables to ignore certain firmware-assigned resources. These
are mostly useful for debugging.
- hw.pci.clear_bars ignores all firmware-assigned ranges for BARs when
  set.
- hw.pci.clear_pcib ignores all firmware-assigned ranges for PCI-PCI
  bridge I/O windows when set.
