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.
