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.
