    mptable: Assign index for each IOAPIC
    IOAPIC information is saved into list ordered by ascending order
    of IOAPIC's APIC ID and each IOAPIC is assigned an index according
    to the order.
    In this way we could use IOAPIC information extracted from ACPI
    MADT and MPTABLE in the same fashion when routing PCI interrupts,
    i.e. using index instead of APIC ID.  It has been observed that on
    some machines, the APIC ID of IOAPIC in ACPI MADT is different from
    the one in MPTABLE, but the order (index) is same.
    PCI interrupt routing information now saves IOAPIC's index instead
    of IOAPIC's APIC ID.
