  Log:
  - Create a pir0 psuedo device as a child of legacy0 if we attach a legacy
    host-PCI bridge device and find a valid $PIR.
  - Make pci_pir_parse() private to pci_pir.c and have pir0's attach routine
    call it instead of having legacy_pcib_attach() call it.
  - Implement suspend/resume support for the $PIR by giving pir0 a resume
    method that calls the BIOS to reroute each link that was already routed
    before the machine was suspended.
  - Dump the state of the routed flag in the links display code.
  - If a link's IRQ is set by a tunable, then force that link to be re-routed
    the first time it is used.
  - Move the 'Found $PIR' message under bootverbose as the pir0 description
    line lists the number of entries already.  The pir0 line also only shows
    up if we are actually using the $PIR which is a bonus.
  - Use BUS_CONFIG_INTR() to ensure that any IRQs used by a PCI link are
    set to level/low trigger/polarity.
