Add code for ACPI PCI link object manipulation.

This allocate the best IRQ to boot-disable devices (have IRQ 0).
Allocated IRQ will be used for PCI interrupt routing when ACPI is
enabled.

Note that verbose messaging enabled for the time being so that
people can easily notice the strange behavior if it happened.
